Important Questions on Transport in Plants
The combination of numbered terms that correctly completes all the following statements is
i. Transport through the phloem is __1__ while transport through the xylem is __2__.
ii. Loading of sugars into the phloem is __3__ at the source.
iii. Movement of water out of the phloem at the sink is __4__.
In "Pressure Flow" hypothesis, sugars are transported from 'source' to 'sink'. The initial steps which occur during this physiological process are shown here.
I. In leaves glucose is converted to sucrose.
II. Sucrose moves from sieve tube cells to companion cells by active transport.
III. Loading of sucrose produces a hypotonic condition in the phloem.
IV. Water in the adjacent xylem moves into phloem by osmosis.
Identify the above correct statements:
Find correct statements from the following A ) Protein transporters are responsible for maximum rates of transport under saturated state B ) Translocation of substances in bulk flow requires hydrostatic pressure gradient C ) Root pressure plays the greatest contribution for upward movement of water in tall plants D ) Transport proteins of endodermal cells are control points for active transport of ions in two directions

The girdling experiment is performed to demonstrate:
Condensation
Transpiration
The correct option is B Transpiration The girdling experiment demonstrates the importance of the phloem tissues. Phloem tissues help in conduction of food (glucose). When a stem is girdled(phloem is removed) the movement of food materials get blocked, and the trunk portion starts swelling due to the accumulation of food materials.

Girdling experiment is used to identify the tissue through which the food is transported. In this experiment a ring of bark (phloem) is removed from the wood by a technique known as girdling. Since the woody xylem part remains intact, water and nutrient reaches the leaves. After the preparation of the photosynthate it is not transported to ...

Girdling in Lille, Northern France. Girdling, also called ring-barking, is the circumferential removal or injury of the bark (consisting of cork cambium or "phellogen", phloem, cambium and sometimes also the xylem) of a branch or trunk of a woody plant.Girdling prevents the tree from sending nutrients from its foliage to its roots, resulting in the death of the tree over time, and can also ...

Ringing or girdling experiment is a strategy was first performed by Hartig (1837) in which the outer tissues (bark) of a stem are detached, and leaving only the xylem and pith unharmed. Water transportation towards the stem is undisrupted, but transportation of food down from the leaves stops at the ring in this process.
