If the xylem tissue of a plant were selectively removed instead of the phloem in a girdling experiment, what would be the most likely observed effect?
Wilting of leaves
Swelling above the girdle
Accumulation of sugars in the roots
Increased fruit production

If the mass flow hypothesis were entirely accurate, which scenario would be LEAST likely to occur in a plant?
Movement of sucrose from a leaf to a developing fruit.
Higher turgor pressure in phloem sieve tubes near a photosynthesizing leaf compared to those near a root tip.
Simultaneous bidirectional transport of different organic molecules within the same sieve tube element.
Changes in phloem sap composition based on the source and sink tissues involved.
In the Girdling Experiment, removal of a ring of bark from a woody stem primarily interrupts the flow of:
Sucrose

Auxins
Gibberellins
Translocation of sucrose takes place through?
Phloem
Xylem
Cambium
Wood Parenchyma
Loading of sucrose in sieve tube elements is
Simple diffusion
Active process
Facilitated diffusion
Osmosis
If the phloem is girdled (ringed) in a tree, which process is MOST directly affected?
Transpiration
Water uptake by roots
Photosynthesis in leaves
Translocation of sugars to the roots
The movement of sucrose into sieve tube elements at the source is primarily achieved through:
Diffusion
Osmosis
Passive transport
Active transport
Ascent of sap in plants was demonstrated by
Girdling experiment
Ganong’s experiment
Went experiment
Lever auxanometer
Choose the false statement
If bark of tree is girdled from main stem, the plant dies because ascent of sap is stopped
If xylem is girdled from main stem, wilting of leaves tales place
In the flowerering plant food is transported in the form of dissacharide sucrose
In Girdling experiment, in a plant, root dies first

II. Food is synthesised in form of glucose by leaf cells
III. Movement of water takes place into sieve tube elements
IV. Downward movement of sugar occurs in the stem
V. Solutes are actively transported into the sieve elements
I, II, III, V, IV
