Question

Water potential is generally most negative in which of the following parts of a plant?
A) mesophyll cells of the leaf
B) xylem vessels in leaves
C) xylem vessels in roots
D) cells of the root cortex

Accepted Answer

Water potential is generally most negative in the mesophyll cells of the leaf, which helps in the movement of water upwards from the roots through the xylem to the leaves due to the gradient in water potential.
