Transport System in Plants & Animals
Solution
The upward movement of the sap in the xylem vessel is brought about by
A
transpiration stream
B
guttation
C
capillarity
D
osmosis
E
cohesion.
medium Difficulty
Verified Correct Answer: Option A
Biological Concept & Syllabus Guide
The upward movement of sap in xylem vessels is primarily driven by transpiration pull, which creates a suction force as water evaporates from the leaves. This force is also supported by the cohesion and adhesion of water molecules and, to a lesser extent, by root pressure.
