flower , the characteristic reproductive structure of angiosperms . As popularly used, the term “flower” especially applies when part or all of the reproductive structure is distinctive in colour and form.

In their range of colour, size, form, and anatomical arrangement, flowers present a seemingly endless variety of combinations. They range in size from minute blossoms to giant blooms. In some plants, such as poppy , magnolia , tulip , and petunia , each flower is relatively large and showy and is produced singly, while in other plants, such as aster , snapdragon , and lilac , the individual flowers may be very small and are borne in a distinctive cluster known as an inflorescence . Regardless of their variety, all flowers have a uniform function, the reproduction of the species through the production of seed .

Basically, each flower consists of a floral axis upon which are borne the essential organs of reproduction ( stamens and pistils ) and usually accessory organs (sepals and petals); the latter may serve to both attract pollinating insects and protect the essential organs. The floral axis is a greatly modified stem; unlike vegetative stems, which bear leaves , it is usually contracted, so that the parts of the flower are crowded together on the stem tip, the receptacle. The flower parts are usually arrayed in whorls (or cycles) but may also be disposed spirally, especially if the axis is elongate. There are commonly four distinct whorls of flower parts: (1) an outer calyx consisting of sepals; within it lies (2) the corolla , consisting of petals ; (3) the androecium , or group of stamens; and in the centre is (4) the gynoecium , consisting of the pistils.

The sepals and petals together make up the perianth , or floral envelope. The sepals are usually greenish and often resemble reduced leaves, while the petals are usually colourful and showy. Sepals and petals that are indistinguishable, as in lilies and tulips, are sometimes referred to as tepals. The androecium, or male parts of the flower, comprise the stamens , each of which consists of a supporting filament and an anther , in which pollen is produced. The gynoecium, or female parts of the flower, comprises one or more pistils , each of which consists of an ovary , with an upright extension, the style, on the top of which rests the stigma , the pollen-receptive surface. The ovary encloses the ovules , or potential seeds. A pistil may be simple, made up of a single carpel , or ovule-bearing modified leaf; or compound , formed from several carpels joined together.

A flower having sepals, petals, stamens, and pistils is complete ; lacking one or more of such structures, it is said to be incomplete . Stamens and pistils are not present together in all flowers. When both are present the flower is said to be perfect , or bisexual, regardless of a lack of any other part that renders it incomplete ( see photograph ). A flower that lacks stamens is pistillate, or female, while one that lacks pistils is said to be staminate, or male. When the same plant bears unisexual flowers of both sexes, it is said to be monoecious (e.g., tuberous begonia, hazel, oak, corn); when the male and female flowers are on different plants, the plant is dioecious (e.g., date, holly , cottonwood, willow); when there are male, female, and bisexual flowers on the same plant, the plant is termed polygamous.

A flower may be radially symmetrical ( see photograph ), as in roses and petunias, in which case it is termed regular or actinomorphic . A bilaterally symmetrical flower, as in orchids ( see photograph ) and snapdragons, is irregular or zygomorphic .

The stamens and pistils are directly involved with the production of seed . The stamen bears microsporangia (spore cases) in which are developed numerous microspores (potential pollen grains); the pistil bears ovules, each enclosing an egg cell. When a microspore germinates, it is known as a pollen grain. When the pollen sacs in a stamen’s anther are ripe, the anther releases them and the pollen is shed. Fertilization can occur only if the pollen grains are transferred from the anther to the stigma of a pistil, a process known as pollination .

There are two chief kinds of pollination: (1) self-pollination , the pollination of a stigma by pollen from the same flower or another flower on the same plant; and (2) cross-pollination , the transfer of pollen from the anther of a flower of one plant to the stigma of the flower of another plant of the same species. Self-pollination occurs in many species, but in the others, perhaps the majority, it is prevented by such adaptations as the structure of the flower, self-incompatibility, and the maturation of stamens and pistils of the same flower or plant at different times. Cross-pollination may be brought about by a number of agents, chiefly insects and wind. Wind-pollinated flowers ( see photograph ) generally can be recognized by their lack of colour, odour , or nectar, while animal-pollinated flowers ( see photograph ) are conspicuous by virtue of their structure, colour, or the production of scent or nectar .

After a pollen grain has reached the stigma, it germinates, and a pollen tube protrudes from it. This tube, containing two male gametes (sperms), extends into the ovary and reaches the ovule , discharging its gametes so that one fertilizes the egg cell, which becomes an embryo , and the other joins with two polar nuclei to form the endosperm . (Normally many pollen grains fall on a stigma; they all may germinate, but only one pollen tube enters any one ovule.) Following fertilization, the embryo is on its way to becoming a seed, and at this time the ovary itself enlarges to form the fruit .

Flowers have been symbols of beauty in most civilizations of the world, and flower giving is still among the most popular of social amenities . As gifts, flowers serve as expressions of affection for spouses, other family members, and friends; as decorations at weddings and other ceremonies; as tokens of respect for the deceased; as cheering gifts to the bedridden; and as expressions of thanks or appreciation. Most flowers bought by the public are grown in commercial greenhouses or horticultural fields and then sold through wholesalers to retail florists.

Parts of Flower and Plant (Pistil, Sepal, Stamen and More) With Diagrams of Flower and Plant

There are many different types of flowers but most of them have the same basic parts. Plant flowers contain female parts called pistil and male parts called stamen which allow the plant to reproduce. The flower is attached to the stalk which is a central shoot that also holds the leaves. The function of the stem is to support the plant and transport nutrients to the leaves and flowers.

Of course, flowers and plants have many other parts, each with its own specific function. In this guide to the parts of flower and plant, you will learn what makes them so amazing. After all, we all use different plant parts in our diet and for their healing benefits.

This article includes anatomy illustrations of the flower, stem, pistil, sepal, stamen and more. This is an extensive guide that includes 7 plant and flower diagrams illustrating their different parts.

Complete Flower Vs. Incomplete Flower

Botanically, a flower is considered to be complete flower if it contains the four main parts of a flower: petals, sepals, stamen, and carpel (also known as a pistil). If a flower lacks any one of these parts, it is an incomplete flower.

Rose, hibiscus and tulip are complete flowers because they have all the main flower organs. The flowers of holly, corn, squash and grasses are incomplete flowers.

Perfect Flower Vs. Imperfect Flower

A flower is considered to a perfect flower when it contains the male (stamen) and female (carpel / pistil) reproductive parts. A perfect flower is also called bisexual bloom because it contains both female and male parts. Flowers that contain either stamen or pistil are called imperfect or unisexual flowers.

Parts of a Flower (Flower Anatomy) Including a Flower Diagram

Flowers are the parts of plants that give them beauty, scent, and they function as the plant’s reproductive system. Flowers attach to the plant via the stalk.

The Structure and Functions of Flowers

A flower has female and male parts. The male part of a flower is the stamen. The female part of a flower is called pistil, and it is composed of parts named stigma, style, and ovary. Petals of various colors surround the male and female reproductive parts.

In a similar way to how the human reproductive systems work, the ovary needs to be fertilized to produce a new baby plant. This happens when pollen lands on the stigma and it releases sperm cells. These travel down the style to the ovary where they fuse with an egg and start to grow.

Parts of a Flower (Diagram of Flower Anatomy With Labels)

Pistil (The Female Part of the Flower)

The pistil functions as the female reproductive part of the flower that comprises of the stigma, style, and ovary.

Sometimes the term carpel is used in place of pistil. In some cases, a carpel and pistil are one and the same thing. However, in some flowers, the 2 or 3 carpels fuse together to form a pistil.

The stigma in flower is the upper part of the pistil that receives the pollen. The stigma sits on top of the style and traps pollen due to its hairy or sticky surface.

Parts and Function of the Ovary in the Flower

When looking at a diagram of a flower, the ovary is the enlarged part located at the base of the pistil. The function of the ovary is to protect its ovules that fertilize pollen that reaches down the pollen tube.

One of the reasons why flowers are necessary for fruit-bearing plants is for fruit to form properly. Once fertilized, the ovary develops into fruit that contains seeds.

Stamen (The Male Part of the Flower)

The stamen is the part of the flower that carries pollen. The stamen is made up of two parts:

• Filament is the hair-like stalk
• Anther is at the end of the stalk and holds the pollen

The sepals are the green leaves surrounding the bud before it flowers. The function of sepals is to protect the flower in the bud stage and also support blooming flowers. The sepal generally falls off after flowering.

The bright color of petals functions as a way to attract bees, insects, and birds that pollinate the plant.

Although petals aren’t directly involved in the plant’s reproductive system, the play an important function.

The petals of some flowers produce scents that either attract or repel certain pollinators. The color of petals is also important to attract pollinators that have a poor sense of smell. Also, larger petals attract pollinators from longer distances.

Petals are actually leaves of the plant the same as sepals are.

Plant Parts and Their Function (Including Diagrams)

Beautiful flowers are just one part of plants that add to their important function. Each part of the plant carries out a specific function to enable the plant grow properly.

The main factors involved in healthy plant growth are sunlight, that gives energy to plants through the leaves, and water and minerals that get absorbed through the root system.

However, many parts of plants have multiple functions. For example, the roots both help keep the plant anchored in the ground and also take in minerals and moisture from the soil. The stems function to both transport water and minerals from the roots to leaves and support the plant.

It is also good to remember that plants also function as the main source of life for humans. Plants are a rich source of nutrients, vitamins, and minerals in our diets. Even meat lovers depend on animals that feed on plant matter for their food.

Many plants also have a healing function and are used in many natural remedies. Extracts from plants in the form of essential oils, tinctures, and juice contain phytochemicals with medicinal properties.

Let’s look in more detail at all the many parts of a plant and their functions.

Parts of a Plant Diagram

Plant Roots

The plant root system is one of the most important parts of the plant and is generally located below ground.

Roots function as the principle way plants get nourishment in the form of water, minerals, and other nutrients.

There are many types of plant root, for example:

Taproot system . Plants with taproots have a large, thick central root from which other hair-like roots develop. Plants that have taproots also function as functional foods. For example, carrots, parsnips, potatoes, beets, and radishes are all example of plants that are good for you.

Fibrous root system . Fibrous root plants have thin small roots that grow downwards and also branch out.

Creeping roots . These shallow and long roots don’t go deep into the soil and can cover a large area.

Tuberous roots . Thick roots that store up food for the plant.

Adventitious roots . Roots that start above the soil from the stem and then go down into the soil.

Function of the Stem

The stem is necessary for the plant to transport nutrients and water throughout the plant and to connect the leaves and flowers. The stems also help to transport food produced by the leaves to the flowers and roots.

Stems are also connected to the function of the leaves to make sure the plant gets enough food. For example, stems need to grow tall enough so that the leaves can get sunlight.

Some types of plant stems are also edible. Some examples of edible stems include asparagus, broccoli, cauliflower, and rhubarb.

The function of leaves is to make food that gives the plant energy and encourages healthy growth.

Leaves come in many shapes, textures, and sizes and are found at the end of stems on plants. Together the leaf and stem form a shoot which is usually the first stage of plant growth.

Plant leaves also breathe by allowing plants to “inhale” and “exhale” air. Leaves also give off moisture and can also absorb moisture through their leaves.

Some plant leaves are simple leaves that only have a single blade and a single main vein. Other leaves called compound leaves and are made up of small leaves that attach to a central stem. Some succulent plants such as aloe vera have thick fleshy leaves that contain a lot of moisture.

Leaves are also important parts of the plant that we eat. The leaves of many plants are a rich source of vitamins and minerals.

Plant Structure Diagram

The function of plant flowers could be broken down into two main parts. There is the reproductive part that is necessary for new plants to grow, and the vegetative part with its leaves and petals.

The main function of flowers is to produce seed. We have already looked at the female part of the flower and male part of the flower that is involved in reproduction.

The 4 parts of the flower involved in reproduction are the following:

• Sepals are the green leaves that protect the bud before it flowers.
• Stamen is the male flower part that has the pollen on it.
• Pistil is the female flower part that contains the stigma, style, pollen tube, and ovaries.
• Petals aren’t involved in the reproduction process but their function is to attract pollinators.

Bright petals, flowers, and colorful blossoms are one of the most attractive parts of any plant.

Flowers and plant blossoms are often consumed in the form of herbal teas and spices. Examples of edible plant flowers include zucchini flowers, nasturtiums and calendula. Essential oils are often produced by extracting the therapeutic properties from flowers.

Fruits are one of the most delicious parts of plants we enjoy eating. Fruits develop in the flower when pollination occurs and egg cells in the ovules are fertilized. The ovules develop into seeds and the ovary begins to ripen.

Some fruits develop into fleshy fruits such as nectarines, lemons, apples, and strawberries. Other “fruits” are hard such as nuts.

Fruits are classed as fleshy edible products of flowering plants that contain a seed. This means that some plant products we tend to think of as vegetables are actually fruits.

For example, tomatoes, eggplants, and bell peppers are actually a type of berry fruit. Cucumbers are also technically classed as fruits because they have a fleshy structure that contains seeds.

Without seeds, new plants can’t grow. Seeds contain all the necessary parts that develop into another plant. Each seed is an embryo that will start to germinate and grow under the right conditions.

The first sign of a seed sprouting is a tiny leaf that is connected to a thin stem. As the sprout grows, it develops roots, the stem becomes thicker, leaves appear, and eventually flowers.

Dioecious Plants Vs. Monoecious Plants

“Dioecious” and “monoecious” are horticultural terms that relate to plant reproduction. Dioecious describes a plant group that includes distinct male and female plants. This means that the male and female flowers are on different plants. Monoecious describes a single plant that have both male and female flowers.

Dioecious and monoecious plants both have unisexual or imperfect flowers.

How Leaf Anatomy Helps Plants to Function

The function of any plant relies on the plant’s leaves. The plant leaf is a small factory that produces energy through a process called photosynthesis. Leaves also produce oxygen and absorb carbon dioxide from the atmosphere.

Chlorophyll is the main chemical in leaves that makes them function properly. This is a green pigment that is responsible for the color of leaves.

The main parts of a leaf are the epidermis, cuticle, veins, and stoma. The cuticle is the waxy surface that covers the epidermis of the leaf. This allows the plant to “breathe” through the stomata (plural of stoma – a tiny opening or pore ) as it draws in carbon dioxide and gives off oxygen. The veins running through the leaf transport nutrients and water throughout the plant.

Leaf structure diagram

Photosynthesis and Plant Function

One of the most important functions of plant leaves is to convert the sun’s rays into energy. This is a process called photosynthesis and is the reason why leaves are green.

For photosynthesis to happen, a number of factors are needed. Photosynthesis requires energy from the sun, carbon dioxide, water, and chlorophyll.

The leaves get water through the plant’s root system and absorb sunlight and carbon dioxide during the daytime. Chlorophyll breaks up water into hydrogen and oxygen. During this process, carbon dioxide and hydrogen combine to produce sugars. This provides energy for the plant and also releases oxygen into the atmosphere.

Parts of Plants and Flowers that are Useful to Us

It is clear to see that plants have an important function in helping to sustain life on earth.

Here are a number of ways that parts of flowers and plants are important for our health:

Food . Many plant leaves, roots, flowers, and stems are edible and are an important source of vitamins, minerals, fiber, and other nutrients.

Medicines . Extracts of many plants have medicinal properties that can help address a number of ailments. Parts of plants can be used to make therapeutic herbal teas, essential oils, or taken as supplements.

Pleasing to the eye . Flowers, blossoms, and colorful petals are pleasing to the eye. Having houseplants or freshly cut flowers can brighten up a room, create pleasant aromas, and may help clean the air.

• Describe the components of a complete flower

The lifecycle of angiosperms follows the alternation of generations explained previously. The haploid gametophyte alternates with the diploid sporophyte during the sexual reproduction process of angiosperms. Flowers contain the plant’s reproductive structures.

A typical flower has four main parts—or whorls—known as the calyx, corolla, androecium, and gynoecium (Figure 1). The outermost whorl of the flower has green, leafy structures known as sepals. The sepals, collectively called the calyx, help to protect the unopened bud. The second whorl is comprised of petals—usually, brightly colored—collectively called the corolla. The number of sepals and petals varies depending on whether the plant is a monocot or dicot. In monocots, petals usually number three or multiples of three; in dicots, the number of petals is four or five, or multiples of four and five. Together, the calyx and corolla are known as the  perianth . The third whorl contains the male reproductive structures and is known as the androecium. The  androecium  has stamens with anthers that contain the microsporangia. The innermost group of structures in the flower is the  gynoecium , or the female reproductive component(s). The carpel is the individual unit of the gynoecium and has a stigma, style, and ovary. A flower may have one or multiple carpels.

Figure 1. The four main parts of the flower are the calyx, corolla, androecium, and gynoecium. The androecium is the sum of all the male reproductive organs, and the gynoecium is the sum of the female reproductive organs. (credit: modification of work by Mariana Ruiz Villareal)

If all four whorls (the calyx, corolla, androecium, and gynoecium) are present, the flower is described as complete. If any of the four parts is missing, the flower is known as incomplete. Flowers that contain both an androecium and a gynoecium are called perfect, androgynous or hermaphrodites. There are two types of incomplete flowers: staminate flowers contain only an androecium, and carpellate flowers have only a gynoecium (Figure 2).

Figure 2. The corn plant has both staminate (male) and carpellate (female) flowers. Staminate flowers, which are clustered in the tassel at the tip of the stem, produce pollen grains. Carpellate flower are clustered in the immature ears. Each strand of silk is a stigma. The corn kernels are seeds that develop on the ear after fertilization. Also shown is the lower stem and root.

Practice Question

If the anther is missing, what type of reproductive structure will the flower be unable to produce?

What term is used to describe an incomplete flower lacking the androecium?

What term describes an incomplete flower lacking a gynoecium?

If both male and female flowers are borne on the same plant, the species is called monoecious (meaning “one home”): examples are corn and pea. Species with male and female flowers borne on separate plants are termed dioecious, or “two homes,” examples of which are C. papaya and Cannabis . The ovary, which may contain one or multiple ovules, may be placed above other flower parts, which is referred to as superior; or, it may be placed below the other flower parts, referred to as inferior (Figure 3).

Figure 3. The (a) lily is a superior flower, which has the ovary above the other flower parts. (b) Fuchsia is an inferior flower, which has the ovary beneath other flower parts.

About Flower

Flowers are introduced as the reproductive part of a plant. They are not only involved in reproduction but are also a source of food for other living organisms. They are a rich source of nectar.

Flowers can either be

• Incomplete.

A complete flower is one that consists of sepals, petals, stamens and pistils. On the contrary, an incomplete flower is one that lacks one or more of these structures.

A complete flower consists of two different parts:

• Vegetative Part
• Reproductive Part

Also read:  Flowers and Inflorescence

Let us have a detailed look at the different parts of a flower.

Flower – L abelled Diagram

Below is a well labelled and simple diagram of a flower for your better understanding.

The calyx, corolla, androecium, and gynoecium are four whorls of modified leaves that constitute the flower. The sepals, petals, stamens, and pistils, respectively, constitute one of the flower parts in each of these whorls.

The different parts of a flower are mentioned below:

Vegetative Parts of a Flower

The vegetative part of a flower consists of the following:

• Petals:  This is a bright-coloured part that attracts bees, insects, and birds. The colour of petals varies from plant to plant; some are bright while some are pale coloured. Thus, petals help us to differentiate one flower from another.
• Sepals:  Sepal is the green-coloured part beneath the petals to protect rising buds .  Some flowers have fused petals-sepals while a few have separated petals-sepals.

Reproductive Parts of a Flower

Flowers contain the plant’s reproductive structures.

In different plants, the number of petals, sepals, stamens and pistils can vary. The presence of these parts differentiates the flower into complete or incomplete. Apart from these parts, a flower includes reproductive parts – the stamen and pistil.  A flower may have only female parts, only male parts, or both.

The reproductive parts of a flower consist of the following:

• Stamen :  This is the male reproductive organ and is also known as Androecium. It consists of two parts namely: anther and filaments.
• The anther is a yellowish, sac-like structure, involved in producing and storing the pollens.
• The filament is a slender, threadlike object, which functions by supporting the anther.
• Pistil:  This is the innermost part and the female reproductive organ of a flower which comprises three parts -stigma, style and ovary. This is collectively known as the pistil.
• Stigma: It is the topmost part or receptive tip of carpels in the gynoecium of a flower.
• Style: It is the long tube-like slender stalk that connects the stigma and the ovary.
• Ovary: It is the ductless reproductive gland that holds a lot of ovules. It is the part of the plant where the seed formation  takes place.

Along with the vegetative and reproductive parts, a flower is also composed of four whorls, which are largely responsible for the  radial   arrangement of a flower. A typical flower has a circular section with a common centre, which can be clearly observed and distinguished from the top of the flower. There four whorls are:

The calyx is the outermost whorl of a flower. It comprises sepals, and tiny leaves present at the base of a flower. These protect the flower whorls against mechanical injuries and desiccation. Some plants have coloured sepals the calyx and are called petaloid.

If the sepals are free the calyx is called polysepalous, and if they are united it is called gamosepalous.

In many flowers, the sepals fall off before the flower even opens fully. Such sepals are known as caducous.

In some, the sepals fall off after fertilization. Such sepals are known as deciduous.

The persistent sepals remain up to the fruiting stage.

This is the second whorl of a flower. It contains petals which serve two main functions:

• To attract pollinators.
• To protect the reproductive parts of a flower

Petals are brightly coloured and scented to attract animals and insects for pollination. The calyx and corolla are collectively called the perianth.

Different forms of the corolla are found in the flowers.

• Polypetalous Regular
• Polypetalous Irregular
• Gamopetalous Regular
• Gamopetalous Irregular

Stamen is also known as the third whorl of the flower and is the male reproductive part. It consists of a filament which is a thread-like structure with a circular structure anther on the top. Pollen is produced by the anther which contributes to the male reproductive process of the plant. All the stamens do not bear fertile anthers.

The carpel is the fourth whorl of the flower present in the centre. The carpels contain the pistil, the female reproductive part of the flower. It comprises the ovary, style, and stigma. The egg or the ovule is present in the ovary. After  fertilization , sometimes the ovary turns into the fruit to keep the seed. At the top of the ovary is a vertical structure called style that supports the stigma. The dispersed pollens stick to the stigma and travel down to the ovary through the style.

This was an overview of the different parts of a flower.

The important functions of flowers are mentioned below:

• Gametophytes develop in the flowers.
• The flowers can produce diaspores without fertilization.
• After fertilization, the ovary of the flower develops into a fruit containing a seed.
• The most important function of flowers is reproduction. They help in the union of male and female gametes.
• Flowers provide nectar to certain birds and insects, which in turn help in the transfer of pollen from one flower to the other.
• Flowers may promote selfing, i.e., the union of sperms and eggs from the same flower, or cross-fertilization, i.e., the union of sperms and eggs from different flowers.

Pollination is the process in which the pollens are transferred from anther to stigma. The process of pollination can occur through a different medium.

The table mentioned below describes the different types of pollination along with their pollinating agents.

How do flowers reproduce?

Flowers reproduce by a process called pollination. In this process, the male gametes are transferred to the female ovules where fertilization occurs and ovules grow into seeds within a fruit.

Give 10 uses of flowers.

History demonstrates that people have been using flowers for various reasons for thousands of years. Ten uses of flowers include:

• Production of food
• Origin of honey
• Origin of medicine
• Promote crop production and pollination
• Enhance the neighbouring area
• Provide fragrances and colognes
• Preparation of dyes
• Pest deterrents
• Promote breeding

What are the reproductive parts of a flower?

Stamen is the male reproductive part of a flower, while pistil is the female reproductive part of a flower. The stamen is surrounded by anther and filament. The anthers produce pollen grains.

Parts of a Flower

(Source: anmh.org)

Most flowers have four main parts: sepals , petals, stamens, and carpels. The stamens are the male part whereas the carpels are the female part of the flower. Most flowers are hermaphrodite where they contain both male and female parts. Others may contain one of the two parts and may be male or female.

Before getting into parts, understand the classification of Flowers here .

• Peduncle: This is the stalk of the flower.
• Receptacle: It is that part of the flower to which the stalk is attached to. It is small and found at the centre of the base of the flower.
• Sepals: These are the small, leaf-like parts growing at the base of the petals. They form the outermost whorl of the flower. Collectively, sepals are known as the calyx. The main function of the calyx and its sepals is to protect the flower before it blossoms(in the bud stage).
• Petals: This layer lies just above the sepal layer. They are often bright in colour as their main function is to attract pollinators such as insects, butterflies etc to the flower. The petals are collectively known as the corolla.
• Filament: the part that is long and slender and attached the anther to the flower.
• Anthers: It is the head of the stamen and is responsible for producing the pollen which is transferred to the pistil or female parts of the same or another flower to bring about fertilization.

(Source: Wikipedia)

• Pistil: This forms the female parts of a flower. A collection of pistils is called the gynoecium.

Learn more about Inflorescence here .

Pistil consists of four parts

(Source: Britannica)

• Style  -is a long slender stalk that holds the stigma. Once the pollen reaches the stigma, the style starts to become hollow and forms a tube called the pollen tube which takes the pollen to the ovaries to enable fertilization.
• Stigma – This is found at the tip of the style. It forms the head of the pistil. The stigma contains a sticky substance whose job is to catch pollen grains from different pollinators or those dispersed through the wind. They are responsible to begin the process of fertilization.
• Ovary – They form the base of the pistil. The ovary holds the ovules.
• Ovules – These are the egg cells of a flower. They are contained in the ovary. In the event of a favorable pollination where a compatible pollen reaches the stigma and eventually reaches the ovary to fuse with the ovules, this fertilized product forms the fruit and the ovules become the seeds of the fruit.

Introduction to Leaf Structure

Solved Example for You

Q: What forms the androecium in a flower?

Sol: The correct option is (b) Stamens

The androecium is the male part of the flower. A collection of stamens is an androecium.

FAQ’s for You

Q1. The flower is important to a plant because it helps in A. Attracting B. Production of Nectar C. Pollination D. All of above

Answer:  All the flowers are important to plant as they attract pollinators by producing nectar, attracting pollinators and helps to plants in the reproduction process by pollination. So, the correct option is ‘All of the above.’

Q2. Which of the following flower contain both stamens and pistils? A. Perfect flower B. Incomplete flower C. Staminate flower D. Bracteate flower

Answer:  A bisexual flower is a flower that contains all the four whorls such as petals, sepals, the male reproductive structure (stamen) and female reproductive structure (pistil). Hence it is also called as a complete or perfect flower.

Q3. What are sessile and pedicellate flowers?

Answer:  A flower which bears a stalk or pedicel is called as a pedicellate flower e.g. Hibiscus, Rose. A flower which is borne directly on the stem is called to be a sessile flower. It is devoid of a stalk. Examples are sunflower florets, Sisyrinchium.

Q4. Flowers, which are pollinated by insects, are?

Answer:  Insects such as butterflies, moths and bees visit flowers for nectar. These flowers have to be large, colored, showy and scented so that they can be easily spotted by insects. While feeding on nectar the pollens attach onto their body. When the same insect visits another flower it transfers the pollen to the stigma of that flower leading to pollination.

Dissect a Flower

A botanical science project from Science Buddies

By Science Buddies & Svenja Lohner

A petal by any other name: Become a budding botanist by learning how each part of a flower works. 

George Retseck

Key Concepts Biology Botany Dissection Plants Reproduction

Introduction Springtime is when nature appears to come back to life after winter. Trees grow leaves, grass gets green, and flowers sprout, displaying beautiful colors and sometimes spreading a delightful scent. But have you ever looked at a flower in more detail? What parts do flowers consist of? Are all flowers alike? In this activity you will find out by dissecting, or taking apart, a flower piece by piece. How many plant parts do you think you can identify?

Background Plants that make flowers are known as flowering plants. But do flowers only exist to make plants look pretty? Not quite! Although they can be beautiful to us, flowers are made to attract pollinators for reproduction. This means the flowers are a crucial part of the process in growing seeds to make more plants. If you look closely at a flower, you might see that it is made of many different parts, each of which has a specific purpose.

Some flowering plants have a stem, which is a long stalk that carries water and nutrients and supports the flower. Leaves produce the food for the plant by photosynthesis, a process that helps makes plant food from light, carbon dioxide and water.

When you look at the flower of a flowering plant, the most obvious parts are probably the petals. They can vary in size and shape but are usually brightly colored. Their purpose is to attract the bees and other insects that help to pollinate the plants. You might be surprised to learn that some flowers­—in the botanical world they are called "perfect flowers"—have male parts and female parts, and each plays an important role during pollination.

The male parts, called stamens, look like long stalks (known as filaments) with a little round shape at their end (called the anther), which contains the plant pollen. This bright yellow or orange dust is what insects carry from one plant to another. Pollination occurs if the pollen gets carried to the female parts of a new flower, called the pistil. The pistil is usually a long stalk located in the center of the flower and is also made up of several parts. Most importantly it contains the ovary at its bottom, which houses the female plant eggs called ovules. When pollen is dropped into the pistil of a flower, the eggs, or ovules, inside the plant ovaries are fertilized. The fertilized ovules then grow into plant seeds, and the ovary becomes the fruit.

As you can see, a flower is much more than just beautiful to look at: it is essential for a plant to create more plants. Take a closer look at the many different plant parts in this activity, and see how they differ from one flower to another!

Three different large fresh flowering plants, such as roses, tulips, lilies, petunias, carnations or irises. You will need at least the stem with a flower attached for each of these. Note: Make sure you select "perfect flowers," which have male (stamen) and female (pistil) plant parts, such as those listed above. If you have allergies to certain plants, make sure that you use an alternative.

Glass or cup with water

Six paper plates

Magnifying glass or hand lens (optional)

At least one additional (intact) specimen of each of the flower types you chose to dissect (optional)

Paper (optional)

Colored pencils (optional)

Poster-sized paper or poster board (optional)

Tape (optional)

One or more vegetables or fruits, such as carrots, beets, asparagus, broccoli, cauliflower, tomatoes, apples, peppers, lettuce, peas, corn or cabbage (optional)

Preparation

Label each of the paper plates with one plant part ("Stem," "Petal," "Leaf," "Pistil" and "Stamen").

Label one extra paper plate "Other."

Draw lines onto each paper plate to divide it into three sections.

Label each section on each plate with a name of one of the three flowering plants.

Carefully look at each of the flowering plants. If you have a magnifying glass, you can use it to examine your plants and their flowers. What does each plant and flower look like?

Choose one of your flowering plants, and start your plant dissection. Use your hands, scissors or tweezers and carefully take apart your plant. Which plant parts can you identify?

Once you have removed one part of the plant, try to identify it, and place it on the corresponding plate. Put it in the section that is labeled with the right plant name. Can you find a plant part for each plate?

If you cannot identify a specific plant part, place it on the "Other" plate.

When you have finished taking the first plant apart look at all its different parts. How do different parts within one plant compare?

Next repeat the dissection with the remaining two flowering plants. Then compare the plant parts on each paper plate. What do you notice about the same plant part from different flowering plants?

Look at all the plant parts that you placed on the "Other" plate. What do you think these plant parts are? How can you find out?

Extra: If you have intact specimens of the types of flowers you dissected, examine these to see how all of the plant parts you identified fit together in the whole flower. How do these vary across different types of flowers?

Extra: Draw each of your flowering plants on a piece of paper. Color your plant and label each part that you identified.

Extra: Make a "plant parts" poster for each plant: Label a piece of paper with the name of one of your plants. Then tape the full flowering plant on one side of the paper. On the other side, tape each plant part into a different section of the paper. Label each plant part, and decorate your poster.

Extra: Did you know that some parts of flowering plants are edible? Look at carrots, beets, asparagus, broccoli, cauliflower, tomatoes, apples, peppers, lettuce, peas, corn or cabbage. Can you find out which parts of each plant we usually eat?

Observations and Results Just from looking at your flowering plants you might have noticed that each plant looks quite different. Obvious differences, for example, are the size or color of a flower. When you dissected the plants, however, you should have been able to identify the same plant parts for each of your plants. Each of them should have had a stem, which might have had some green leaves on it; colorful flower petals; the female flower part (pistil) at the center of the flower; and the male plant parts (stamen) that produce the pollen. When you compare each plant part you might have noticed that they each look very different. A petal, for example, probably looked very different from the stem. This is because each plant part has a specific function, and its appearance is optimized to fulfill that function.

If you compare the same plant parts between different flowers, you might have observed that they looked somewhat similar. They might not have looked exactly the same, but you should have seen that they have the same functional features. Although flower petals can differ in size and color, they are usually brightly colored or shaped in a way to attract pollinators, such as bees. The differences between different flowering plants allow us to identify different plant species.

Cleanup You can put any remaining intact flowering plants into a jar or vase with water. Discard all the dissected flower parts in your compost or trash. Clean your work area, and wash your hands with water and soap.

Parts of Flower with Types and Functions

In this post, we explore the Parts of a Flower . A flower has several parts. The sepals cover the outside and protect the flower when it’s a bud. The petals are the colorful part we all see and like. Inside, the stamen and pistil are the parts that help the flower make seeds. These Parts of a Flower are important for making new plants.

The flower is the reproductive structure of flowering plants, playing a crucial role in the life cycle of these organisms. The combination of these parts showcases the intricate adaptations that have evolved to ensure the reproductive success of flowering plants. Their diversity in size, shape, color, and fragrance reflects the plant kingdom’s ability to attract and utilize various pollinators for successful reproduction and genetic diversity. The beauty of flowers goes beyond aesthetics, serving as a testament to the intricate processes that sustain plant life.

Table of Contents

What is a Flower?

A flower is the reproductive structure of angiosperms, which are flowering plants. Angiosperms represent the most diverse group of plants on Earth, and their reproductive strategy involves the production of flowers to facilitate sexual reproduction.

Parts of Flower

These parts work together to facilitate pollination, fertilization, and seed development. The diversity in flower structure and appearance reflects adaptations to different pollination methods and environmental conditions. Keep in mind that the presence and characteristics of these parts can vary among different plant species.

Reproductive Parts

Reproductive parts of a flower are like the plant’s matchmakers, playing a crucial role in the process of making seeds. They come in two main types:

1. Stamen (Male Reproductive Part):

• Anther: This is like the pollen factory. It sits on top of the stamen and produces pollen, which contains the plant’s male reproductive cells.
• Filament: Think of it as the supportive stem holding up the anther.

2. Pistil or Carpel (Female Reproductive Part):

• Stigma: Imagine this as a catcher’s mitt. It’s at the top of the pistil and catches pollen.
• Style: Picture it as the tube connecting the catcher’s mitt (stigma) to the base.
• Ovary: The base of the pistil is like the seed vault. It holds ovules, which turn into seeds after they meet up with pollen.

Non-Reproductive Parts

Non-reproductive parts of a flower are like the supporting cast – they may not be directly involved in making seeds, but they play important roles in the flower’s life. Here are two key players:

• Role: Think of sepals as the flower’s bodyguards. They’re the outermost layer, usually green, and their main job is to shield the delicate bud before it blooms into a full-fledged flower.
• Role: Petals are like the flashy billboards of the flower world. They’re often colorful and fragrant, luring in pollinators like bees or butterflies. Though they don’t make seeds themselves, they’re essential for attracting the right attention to ensure successful reproduction.

Accessory Parts

Accessory parts of a flower are like the behind-the-scenes crew, not the stars, but essential for the whole show to run smoothly. Let’s meet them:

1. Peduncle:

• Role: Picture the peduncle as the flower’s supporting actor. It’s the stalk that plays a key role in holding up the entire flower, connecting it to the main plant stem.

2. Receptacle:

• Role: The receptacle is like the stage where all the action happens. It’s the tip of the peduncle, the meeting point for all the floral organs. Everything from sepals to petals gathers here.

Supporting Structures

Supporting structures in a plant are the backbone, the unsung heroes that keep everything upright and connected. Let’s meet them:

• Role: The stem is like the plant’s sturdy spine. It supports not just the flower but the entire plant. It’s a multitasker, transporting water, nutrients, and sugars between different parts.
• Role: Leaves are the solar panels of the plant world. They catch sunlight and turn it into energy through a process called photosynthesis. This energy helps the plant grow and thrive.

Functions of Flower

Flowers serve various essential functions in the life cycle and reproduction of flowering plants. Here are the key functions of flowers:

1. Reproduction:

• Pollination: Helps transfer pollen for fertilization.
• Fertilization: Results in seed development in the ovary.

2. Seed Formation and Dispersal:

• Seeds develop within the ovary.
• Fruits aid in spreading seeds.

3. Attracting Pollinators:

• Bright colors and scents lure pollinators.
• Nectar serves as a sweet reward.

4. Protecting Developing Buds:

• Sepals act as protective shields.

5. Environmental Adaptations:

• Blooming times adjust to seasons.
• Specialized structures enhance pollination.

6. Genetic Variation:

• Cross-pollination promotes diversity.

7. Aesthetic Appeal:

• Diverse colors and shapes enhance beauty.

8. Cultural and Symbolic Significance:

• Used in rituals and celebrations.
• Symbolic representation of emotions.

The main parts of a flower include the reproductive organs (stamen and pistil), non-reproductive parts (sepals and petals), and supporting structures (peduncle and receptacle).

Q2: How do reproduce?

It reproduces through a process called pollination, where pollen containing male gametes is transferred to the female reproductive parts, leading to fertilization and seed development.

Q3: What is the role of sepals in a flower?

Sepals protect the developing bud before it blooms into a flower. They are the outermost layer and act as shields.

Q4: Why do flowers have colorful petals?

Colorful petals attract pollinators such as insects or birds. The vibrant hues serve as visual signals to encourage pollination.

Q5: How does the ovary contribute to seed formation?

The ovary, located at the base of the pistil, contains ovules. After fertilization, the ovules develop into seeds, and the ovary often matures into a fruit.

Q6: What is the role of the receptacle in a flower?

The receptacle is the tip of the peduncle where floral organs are attached. It provides support and acts as the meeting point for all the parts.

Essay on Flowering Plants

• Essay on the Fruit and Seed of Flowering Plants  

ADVERTISEMENTS: (adsbygoogle = window.adsbygoogle || []).push({}); 1. Essay on the Introduction to Flowering Plants:

The flowering plants or angiosperms (Angiospermae or Magnoliophyta) are the most diverse group of land plants. The flowering plants and the gymnosperms are the only extant groups of seed plants. The flowering plants are distinguished from other seed plants by a series of apomorphies, or derived characteristics.

The ancestors of flowering plants diverged from gymnosperms around 245-202 million years ago, and the first flowering plants known to exist are from 140 million years ago. They became widespread around 100 million years ago, but replaced conifers as the dominant trees only around 60-100 million years ago.

2. Essay on the Angiosperm Derived Characteristics of Flowering Plants:

The flowers, which are the reproductive organs of flowering plants, are the most remarkable feature distinguishing them from other seed plants. Flowers aid angiosperms by enabling a wider range of adaptability and broadening the ecological niches open to them. This has allowed flowering plants to largely dominate terrestrial ecosystems.

Stamens with Two Pairs of Pollen Sacs:

Stamens are much lighter than the corresponding organs of gymnosperms and have contributed to the diversification of angiosperms through time with adaptations to specialized pollination syndromes, such as particular pollinators. Stamens have also become modified through time to prevent self-fertilization, which has permitted further diversification, allowing angiosperms eventually to fill more niches.

Reduced Male Parts, Three Cells:

The male gametophyte in angiosperms is significantly reduced in size compared to those of gymnosperm seed plants. The smaller pollen decreases the time from pollination — the pollen grain reaching the female plant — to fertilization of the ovary; in gymnosperms fertilization can occur up to a year after pollination, while in angiosperms the fertilization begins very soon after pollination. The shorter time leads to angiosperm plants setting seeds sooner and faster than gymnosperms, which is a distinct evolutionary advantage.

Closed carpel enclosing the ovules (carpel or carpels and accessory parts may become the fruit).

The closed carpel of angiosperms also allows adaptations to specialized pollination syndromes and controls. This helps to prevent self-fertilization, thereby maintaining increased diversity. Once the ovary is fertilized, the carpel and some surrounding tissues develop into a fruit. This fruit often serves as an attractant to seed-dispersing animals. The resulting cooperative relationship presents another advantage to angiosperms in the process of dispersal.

Reduced Female Gametophyte, Seven Cells with Eight Nuclei:

The reduced female gametophyte, like the reduced male gametophyte, may be an adaptation allowing for more rapid seed set, eventually leading to such flowering plant adaptations as annual herbaceous life cycles, allowing the flowering plants to fill even more niches.

Endosperm :

Endosperm formation generally begins after fertilization and before the first division of the zygote. Endosperm is a highly nutritive tissue that can provide food for the developing embryo, the cotyledons, and sometimes for the seedling when it first appears.

These distinguishing characteristics taken together have made the angiosperms the most diverse and numerous land plants and the most commercially important group to humans. The major exception to the dominance of terrestrial ecosystems by flowering plants is the coniferous forest.

Land plants have existed for about 425 million years. Early land plants reproduced sexually with flagellated, swimming sperm, like the green algae from which they evolved. An adaptation to terrestrialization was the development of upright meiosporangia for dispersal by spores to new habitats. This feature is lacking in the descendants of their nearest algal relatives, the Charophycean green algae.

A later terrestrial adaptation took place with retention of the delicate, a vascular sexual stage, the gametophyte, within the tissues of the vascular sporophyte. This occurred by spore germination within sporangia rather than spore release, as in non-seed plants. A current example of how this might have happened can be seen in the precocious spore germination in Sellaginella, the spike-moss.

The result for the ancestors of angiosperms was enclosing them in a case, the seed. The first seed bearing plants, like the ginkgo, and conifers (such as pines and firs), did not produce flowers. Interestingly, the pollen grains (males) of Ginkgo and cycads produce a pair of flagellated, mobile sperm cells that ‘swim’ down the developing pollen tube to the female and her eggs.

The apparently sudden appearance of relatively modern flowers in the fossil record posed such a problem for the theory of evolution that it was called an ‘abominable mystery’ by Charles Darwin. However, the fossil record has grown since the time of Darwin, and recently discovered angiosperm fossils such as Archaefructus, along with further discoveries of fossil gymnosperms, suggest how angiosperm characteristics may have been acquired in a series of steps.

Several groups of extinct gymnosperms, particularly seed ferns, have been proposed as the ancestors of flowering plants but there is no continuous fossil evidence showing exactly how flowers evolved. Some older fossils, such as the upper Triassic Sanmiguelia, have been suggested. Based on current evidence, some propose that the ancestors of the angiosperms diverged from an unknown group of gymnosperms during the late Triassic (245-202 million years ago).

A close relationship between angiosperms and gnetophytes, proposed on the basis of morphological evidence, has more recently been disputed on the basis of molecular evidence that suggest gnetophytes are instead more closely related to other gymnosperms.

The earliest known angiosperm macrofossil, Archaefructus liaoningensis, is dated to about 125 million years BP (the Cretaceous period), while pollen considered to be of angiosperm origin takes the fossil record back to about 130 million years BP. There is, however, circumstantial chemical evidence for the existence of angiosperms as early as 250 million years ago.

Oleanane, a secondary metabolite produced by many flowering plants, has been found in Permian deposits of that age together with fossils of gigantopterids Gigantopterids are a group of extinct seed plants that share many morphological traits with flowering plants, although they are not known to have been flowering plants themselves.

Recent DNA analysis (molecular systematics) show that Amborella trichopoda, found on the Pacific island of New Caledonia, belongs to a sister group of the other flowering plants, and morphological studies suggest that it has features that may have been characteristic of the earliest flowering plants.

The great angiosperm radiation, when a great diversity of angiosperms appears in the fossil record, occurred in the mid-Cretaceous (approximately 100 million years ago). However, a study in 2007 estimated that the division of the five most recent (the genus Ceratophyllum, the family Chloranthaceae, the eudicots, the magnoliids, and the monocots) of the eight main groups occurred around 140 million years ago.

By the late Cretaceous, angiosperms appear to have dominated environments formerly occupied by ferns and cycadophytes, but large canopy-forming trees replaced conifers as the dominant trees only close to the end of the Cretaceous 65 million years ago or even later, at the beginning of the Tertiary.

The radiation of herbaceous angiosperm occurred much later. Yet, many fossil plants recognizable as belonging to modern families (including beech, oak, maple, and magnolia) appeared already at late Cretaceous.

It is generally assumed that the function of flowers, from the start, was to involve mobile animals in their reproduction processes. That is, pollen can be scattered even if the flower is not brightly colored or oddly shaped in a way that attracts animals; however, by expending the energy required to create such traits, angiosperms can enlist the aid of animals and thus reproduce more efficiently.

Island genetics provides one proposed explanation for the sudden, fully developed appearance of flowering plants. Island genetics is believed to be a common source of speciation in general, especially when it comes to radical adaptations that seem to have required inferior transitional forms.

Flowering plants may have evolved in an isolated setting like an island or island chain, where the plants bearing them were able to develop a highly specialized relationship with some specific animal (a wasp, for example).

Such a relationship, with a hypothetical wasp carrying pollen from one plant to another much the way fig wasps do today, could result in both the plant(s) and their partners developing a high degree of specialization. Note that the wasp example is not incidental; bees, which apparently evolved specifically due to mutualistic plant relationships, are descended from wasps.

Animals are also involved in the distribution of seeds. Fruit, which is formed by the enlargement of flower parts, is frequently a seed-dispersal tool that attracts animals to eat or otherwise disturb it, incidentally scattering the seeds it contains. While many such mutualistic relationships remain too fragile to survive competition and spread widely, flowering proved to be an unusually effective means of reproduction, spreading (whatever its origin) to become the dominant form of land plant life.

Flower ontogeny uses a combination of genes normally responsible for forming new shoots The most primitive flowers are thought to have had a variable number of flower parts, often separate from (but in contact with) each other.

The flowers would have tended to grow in a spiral pattern, to be bisexual (in plants, this means both male and female parts on the same flower), and to be dominated by the ovary (female part). As flowers grew more advanced, some variations developed parts fused together, with a much more specific number and design, and with either specific sexes per flower or plant, or at least ‘ovary inferior’.

Flower evolution continues to the present day; modern flowers have been so profoundly influenced by humans that some of them cannot be pollinated in nature. Many modern, domesticated flowers used to be simple weeds, which only sprouted when the ground was disturbed.

Some of them tended to grow with human crops, perhaps already having symbiotic companion plant relationships with them, and the prettiest did not get plucked because of their beauty, developing a dependence upon and special adaptation to human affection.

The botanical term ‘Angiosperm’, from the Ancient Greek, angeion (receptacle, vessel) and, (seed), was coined in the form Angiospermae by Paul Hermann in 1690, as the name of that one of his primary divisions of the plant kingdom.

This included flowering plants possessing seeds enclosed in capsules, distinguished from his Gymnospermae, or flowering plants with achenial or schizo-carpic fruits, the whole fruit or each of its pieces being here regarded as a seed and naked. The term and its antonym were maintained by Carolus Linnaeus with the same sense, but with restricted application, in the names of the orders of his class Didynamia.

Its use with any approach to its modern scope only became possible after 1827, when Robert Brown established the existence of truly naked ovules in the Cycadeae and Coniferae, and applied to them the name Gymnosperms. From that time onwards, so long as these Gymnosperms were, as was usual, reckoned as dicotyledonous flowering plants, the term Angiosperm was used antithetically by botanical writers, with varying scope, as a group-name for other dicotyledonous plants.

In 1851, Hofmeister discovered the changes occurring in the embryo-sac of flowering plants, and determined the correct relationships of these to the Cryptogamia. This fixed the position of Gymnosperms as a class distinct from Dicotyledons, and the term Angiosperm then gradually came to be accepted as the suitable designation for the whole of the flowering plants other than Gymnosperms, including the classes of Dicotyledons and Monocotyledons. This is the sense in which the term is used today.

In most taxonomies, the flowering plants are treated as a coherent group. The most popular descriptive name has been Angiospermae (Angiosperms), with Anthophyta (‘flowering plants’) a second choice. These names are not linked to any rank. The Wettstein system and the Engler system use the name Angiospermae, at the assigned rank of subdivision.

The Reveal system treated flowering plants as subdivision Magnoliophytina, but later split it to Magnoliopsida, Liliopsida and Rosopsida. The Takhtajan system and Cronquist system treat this group at the rank of division, leading to the name Magnoliophyta (from the family name Magnoliaceae).

The Dahlgren system and Thorne system (1992) treat this group at the rank of class, leading to the name Magnoliopsida. However, the APG system, of 1998, and the APG II system, of 2003, do not treat it as a formal taxon but rather treat it as a clade without a formal botanical name and use the name angiosperms for this clade.

The internal classification of this group has undergone considerable revision. The Cronquist system, proposed by Arthur Cronquist in 1968 and published in its full form in 1981, is still widely used, but is no longer believed to accurately reflect phylogeny.

A general consensus about how the flowering plants should be arranged has recently begun to emerge, through the work of the Angiosperm Phylogeny Group, who published an influential reclassification of the angiosperms in 1998. An update incorporating more recent research was published as APG II in 2003.

Recent studies, as by the APG, show that the monocots form holophyletic or monophyletic group; this clade is given the name monocots. However, the dicots are not (they are a paraphyletic group). Nevertheless, within the dicots a monophyletic group does exist, called the eudicots or tricolpates, and including most of the dicots. The name tricolpates derives from a type of pollen found widely within this group.

The name eudicots is formed combining dicot with the prefix eu- (from Greek, for ‘well’, or ‘good’, botanically indicating ‘true’), as the eudicots share the characters traditionally attributed to the dicots, such as flowers with four or five parts (four or five petals, four or five sepals).

Separating this group of eudicots from the rest of the (former) dicots leaves a remainder, which sometimes are called informally palaeodicots (Greek prefix ‘palaeo-‘means ‘old’). As this remnant group is not monophyletic this is a term of convenience only.

3. Essay on the Flowering Plant Diversity :

The number of species of flowering plants is estimated to be in the range of 250,000 to 400,000. The number of families in APG (1998) was 462. In APG II (2003) it is not settled; at maximum it is 457, but within this number there are 55 optional segregates, so that the minimum number of families in this system is 402.

The diversity of flowering plants is not evenly distributed. Nearly all species belong to the eudicot (75%), monocot (23%) and magnoliid (2%) clades. The remaining 5 clades contain a little over 250 species in total, i.e., less than 0.1 per cent of flowering plant diversity, divided among 9 families.

The amount and complexity of tissue-formation in flowering plants exceeds that of Gymnosperms. The vascular bundles of the stem are arranged such that the xylem and phloem form concentric rings.

In the Dicotyledons, the bundles in the very young stem are arranged in an open ring, separating a central pith from an outer cortex. In each bundle, separating the xylem and phloem, is a layer of meristem or active formative tissue known as cambium. By the formation of a layer of cambium between the bundles (inter-fascicular cambium) a complete ring is formed, and a regular periodical increase in thickness results from the development of xylem on the inside and phloem on the outside.

The soft phloem becomes crushed, but the hard wood persists and forms the bulk of the stem and branches of the woody perennial. Owing to differences in the character of the elements produced at the beginning and end of the season, the wood is marked out in transverse section into concentric rings, one for each season of growth, called annual rings.

Among the Monocotyledons, the bundles are more numerous in the young stem and are scattered through the ground tissue. They contain no cambium and once formed the stem increases in diameter only in exceptional cases.

Traditionally, the flowering plants are divided into two groups, which in the Cronquist system are called Magnoliopsida (at the rank of class, formed from the family name Magnoliacae) and Liliopsida (at the rank of class, formed from the family name Liliaceae).

Other descriptive names allowed by Article 16 of the ICBN include Dicotyledones or Dicotyledoneae, and Monocotyledones or Monocotyledoneae, which have a long history of use. In English a member of either group may be called a dicotyledon (plural dicotyledons) and monocotyledon (plural monocotyledons), or abbreviated, as dicot (plural dicots) and monocot (plural monocots).

These names derive from the observation that the dicots most often have two cotyledons, or embryonic leaves, within each seed. The monocots usually have only one, but the rule is not absolute either way. From a diagnostic point of view the number of cotyledons is neither a particularly handy nor reliable character.

The characteristic feature of angiosperms is the flower. Flowers show remarkable variation in form and elaboration, and provide the most trustworthy external characteristics for establishing relationships among angiosperm species. The function of the flower is to ensure fertilization of the ovule and development of fruit containing seeds. The floral apparatus may arise terminally on a shoot or from the axil of a leaf (where the petiole attaches to the stem).

Occasionally, as in violets, a flower arises singly in the axil of an ordinary foliage-leaf. More typically, the flower-bearing portion of the plant is sharply distinguished from the foliage- bearing or vegetative portion, and forms a more or less elaborate branch-system called an inflorescence.

The reproductive cells produced by flowers are of two kinds. Microspores, which will divide to become pollen grains, are the ‘male’ cells and are borne in the stamens (or microsporophylls). The ‘female’ cells called megaspores, which will divide to become the egg-cell (megagameto- genesis), are contained in the ovule and enclosed in the carpel (or megasporophyll).

The flower may consist only of these parts, as in willow, where each flower comprises only a few stamens or two carpels. Usually other structures are present and serve to protect the sporophylls and to form an envelope attractive to pollinators. The individual members of these surrounding structures are known as sepals and petals (or tepals in flowers such as Magnolia where sepals and petals are not distinguishable from each other).

The outer series (calyx of sepals) is usually green and leaf-like, and functions to protect the rest of the flower, especially the bud. The inner series (corolla of petals) is generally white or brightly coloured, and is more delicate in structure. It functions to attract insect or bird pollinators.

Attraction is effected by colour, scent, and nectar, which may be secreted in some part of the flower. The characteristics that attract pollinators account for the popularity of flowers and flowering plants among humans.

While the majority of flowers are perfect or hermaphrodite (having both male and female parts in the same flower structure), flowering plants have developed numerous morphological and physiological mechanisms to reduce or prevent self-fertilization.

Heteromorphic flowers have short carpels and long stamens, or vice versa, so animal pollinators cannot easily transfer pollen to the pistil (receptive part of the carpel). Homomorphic flowers may employ a biochemical (physiological) mechanism called self- incompatibility to discriminate between self-and non-self-pollen grains. In other species, the male and female parts are morphologically separated, developing on different flowers.

Double fertilization refers to a process in which two sperm cells fertilize cells in the ovary. This process begins when a pollen grain adheres to the stigma of the pistil (female reproductive structure), germinates, and grows a long pollen tube. While this pollen tube is growing, a haploid generative cell travels down the tube behind the tube nucleus.

The generative cell divides by mitosis to produce two haploid (n) sperm cells. As the pollen tube grows, it makes its way from the stigma, down the style and into the ovary. Here the pollen tube reaches the micropyle of the ovule and digests its way into one of the synergids, releasing its contents (which include the sperm cells).

The synergid that the cells were released into degenerates and one sperm makes its way to fertilize the egg cell, producing a diploid (2n) zygote. The second sperm cell fuses with both central cell nuclei, producing a triploid (3n) cell. As the zygote develops into an embryo, the triploid cell develops into the endosperm, which serves as the embryo’s food supply. The ovary now will develop into fruit and the ovule will develop into seed.

4. Essay on the Fruit and Seed of Flowering Plants :

As the development of embryo and endosperm proceeds within the embryo-sac, the sac wall enlarges and combines with the nucellus (which is likewise enlarging) and the integument to form the seed-coat. The ovary wall develops to form the fruit or pericarp, whose form is closely associated with the manner of distribution of the seed.

The character of the seed-coat bears a definite relation to that of the fruit. They protect the embryo and aid in dissemination; they may also directly promote germination. Among plants with indehiscent fruits, the fruit generally provides protection for the embryo and secures dissemination. In this case, the seed-coat is only slightly developed. If the fruit is dehiscent and the seed is exposed, the seed-coat is generally well developed, and must discharge the functions otherwise executed by the fruit.

Agriculture is almost entirely dependent on angiosperms, either directly or indirectly through livestock feed. Of all the families plants, the Poaceae, or grass family, is by far the most important, providing the bulk of all feed stocks (rice, corn – maize, wheat, barley, rye, oats, pearl millet, sugar cane, sorghum). The Fabaceae, or legume family, comes in second place.

Also of high importance are the Solanaceae, or nightshade family (potatoes, tomatoes, and peppers, among others), the Cucurbitaceae, or gourd family (also including pumpkins and melons), the Brassicaceae, or mustard plant family (including rapeseed and cabbage), and the Apiaceae, or parsley family. Many of our fruits come from the Rutaceae, or rue family, and the Rosaceae, or rose family (including apples, pears, cherries, apricots, plums, etc.).

In some parts of the world, certain single species assume paramount importance because of their variety of uses, for example the coconut (Cocos nucifera) on Pacific atolls, and the olive (Olea europaea) in the Mediterranean region.

Flowering plants also provide economic resources in the form of wood, paper, fiber (cotton, flax, and hemp, among others), medicines (digitalis, camphor), decorative and landscaping plants, and many other uses. The main area in which they are surpassed by other plants is timber production.

Parts of the Flower

Parts Of The Flower A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants. The biological function of a flower is to effect reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing or allow selfing. Many flowers have evolved to be attractive to animals, so that they can be vectors for the transfer of pollen. 1.) Pistil- It is the female reproductive part of the flower. Located in the center of the flower. Often vase-shaped, the pistil consists of three parts: the stigma, the style and the ovary. * Stigma- It is the reception are for the pollen.

The stigma is adapted to catch and trap pollen with various hairs, flaps, or sculpturings The pollen may be captured from the air ,from visiting insects or other animals , or in rare cases from surrounding water. It is sticky and velvety in texture . * Style- It is a slender stalk for the passage of pollen nuclei . Located between ovary and stigma * Ovary- Is the enlarged basal portion that contains one or more ovule-bearing units called carpels. Each ovule contains the female gamete, the egg & 2 polar bodies, which become the endosperm.

2.) Stamen- Is the male reproductive structure of a flower. It is consist of 4 pollen-containing chambers that are fused into a structure called Anther. Inside the anther are the pollen grains , each of which contains the male gamete and the generate sperm nucleus. The Filament supports & hold the anther to the pistil. 3.) Sepals- They are known as the CALYX . They form the outermost part surrounding & holding the petals & at the same time, protecting part of the inner part of a flower. 4.) Petals- Known as the COROLLA, are typically the brightly coloured parts of the flower. They have aromatic substance & nectar which are used to attract insect pollinators. The tip to which the floral organ are attaches are called RECEPRACLES. The PEDUNCLE is the stalk of a single Flower .

2 Main Parts of Typical Flower * Essential Parts – are those directly involved in sexual reproduction . These include the pistil & the stamen * Accessory Parts- are those that are not directly involved in sexual reproduction but facilitate it. These include the sepal, petals, floral bracts and receptacle. ~>Floral

Bracts – modified leaves which can simulate petals and add the conspicuous part to otherwise inconspicuous flowers. Examples are the red bracts surrounding the small Euphorbia ,poinsettia, and bougainvillea. Many plants have floral bracts which are not colourful such as Fittonia vershaffeltii (silver nerve plant).

~> Receptacle – the apex of the pedicel upon which the organs of a flower are developed. Complete and Incomplete Flower

Besides petals, most flowers have a stamen, a pistil and sepals. If a flower has all four of these parts, botanists consider it “complete.” A rose, for example, is a complete flower. If one of these parts is missing, the flower is called “incomplete.” A begonia is an incomplete flower, because its flowers have either a stamen or a pistil, but not both.

Incomplete Flower Complete Flower Cherries Flower Roses

Regular and Irregular Flower * Regular flower is a flower with petals and sepals arranged around the center like the spokes of a wheel and that is thus radially symmetrical. * Irregular flower is a flower with petals that are not uniform in size or shape.

Irregular Flower Daisy Violet Regular Flower Nasturtium Day Lillies Zinnia

Perfect and Imperfect Flower * Perfect flowers are flowers that have both Carpels (Female Organs) and Stamen (Male Organs). This enables them to perform self-pollination. * Imperfect Flowers are flowers that have either a carpel or stamen, but they cannot have both. Imperfect Flowers

US government will loan $1.45 billion to help a South Korean firm build a solar plant in Georgia

ATLANTA (AP) — The federal government is making its first loan to a crystalline silicon solar plant, loaning $1.45 billion to support a South Korean company’s bid to build up key parts of the solar supply chain inside the United States.

The loan from the U.S. Energy Department, announced Thursday, will be key to funding a $2.2 billion complex that Qcells, a unit of South Korea’s Hanwha Group, is building. The company plans to take polysilicon refined in Washington state and make ingots, wafers and solar cells — the building blocks of finished solar modules — in Cartersville, Georgia, northwest of Atlanta.

President Joe Biden’s Inflation Reduction Act , besides offering a extra tax credit on American-made solar equipment, lets manufacturers earn incentives for every unit of polysilicon they refine and every wafer, cell and module they make.

“This loan is special, because it’s one of the first facilities where we’re not just making modules, but we’re making cells and wafers as well,” Jigar Shah, director of the Energy Department’s loan programs, said in a telephone interview Wednesday with The Associated Press. “So we’re bringing a lot more of the supply chain into the United States.”

Qcells in April began assembling modules in part of the complex, which will have a capacity of 3.3 gigawatts of solar panels each year. The plant in Cartersville currently has about 750 employees and is projected to have 2,000 when complete. Qcells says it’s on track to complete the wafer and cell portions of the plant by December.

The company also has a $630 million plant in Dalton, farther northwest in Georgia, with a capacity of 5.1 gigawatts a year. That 1,800-employee plant was built without government loans. The company imports the cells for the Dalton plant.

The Cartersville plant would be the largest ingot and wafer plant built in the United States, the Energy Department said. Between the Dalton and Cartersville plants, Qcells will produce enough solar panels to power nearly 1.3 million homes per year, reducing carbon dioxide emissions from power generation.

Microsoft Corp. has contracted to buy a significant portion of the Cartersville plant’s output over eight years.

Qcells must meet certain conditions for the loan, and Marta Stoepker, a company spokesperson, said Qcells is confident that it will meet the requirements.

“The loan that we’re getting is going to be massively critical for us to stay on track with our goal of really onshoring the supply chain and making it in America,” Stoepker said.

Still, the company said the Biden administration needs to stay committed to supporting domestic solar manufacturing in the face of a continuing surge of cheap imports from Asia, which has caused solar panel prices to fall. Qcells and other manufacturers are pushing for tariffs to protect against what they say is below-cost dumping by companies in Cambodia, Malaysia, Thailand and Vietnam that have ties to China. Stoepker said the Biden administration also could help by refining guidance on the tax credit bonus for American-made solar components.

Shah defended the administration’s efforts, saying supports for the industry are “providing a lot of stability for folks to invest.”

He said the United States is on track to have a reliable domestic supply chain capable of meeting most of its solar panel needs.

“The domestic demand for solar modules in 2026 is expected to be around 50 gigawatts. We’re expecting to produce about 40 gigawatts in 2026,” Shah said. “So that means 80% of the modules that we deploy in the United States in 2026 is expected to be domestic.”

U.S. Sen. Jon Ossoff, a Georgia Democrat who has been the foremost cheerleader for the Biden administration’s support of clean energy projects in the state, said the loan will “continue growing our economy and strengthening American energy independence.”

My Favorite Simone Biles Moment Wasn’t When She Won Gold

By Liriel Higa

Opinion Audience Director

GOAT. Most decorated. Winningest. It sounds hokey, but the most satisfying and joyful part of the Olympics for me is not which country is leading the medal count but when the best athletes in the world show their respect and admiration for one another, especially after an underperformance. On Monday, the last day of the artistic gymnastics competition, Simone Biles and Jordan Chiles, the Americans who took silver and bronze medals in the floor exercise final, showed such sportsmanship to Brazil’s Rebeca Andrade, who won gold.

During the medal ceremony, Biles and Chiles bowed down to the Brazilian as she climbed the podium to receive her medal. Andrade had already come in second to Biles in the all-around and vault event finals , but she took advantage of Biles’s two out-of-bounds landings to take first on floor.

Andrade was runner-up to Biles at the 2023 World Championships and second to Suni Lee at the Tokyo Olympics all-around. It may have been frustrating to keep coming in second, but she has been consistently supportive over the years, saying, for instance, that it was an “honor” to compete against Biles.

For her part, Biles has acknowledged her own fallibility, and reminded us that just because she makes winning look easy does not mean that it is. After the all-around final, Biles said of Andrade: “She’s way too close. I’ve never had an athlete that close, so it definitely put me on my toes, and it brought out the best athlete in myself.”

Of course, it’s easy to be gracious when you’ve won the gold. On Monday, in what might be her final Olympic performance, Biles took the silver on floor after a disappointing fifth-place finish on the balance beam. But when Chiles suggested that they bow down to Andrade, Biles eagerly agreed, creating one of the most iconic images from these Olympics.

Chiles explained their thinking during an interview after the competition. “Why don’t we just give her her flowers,” she said. “Not only has she given Simone her flowers, but a lot of us in the United States our flowers as well. So giving it back is what makes it so beautiful. So, I felt like it was needed.”
