Question

Explain how the movement of water takes place in a tree during day and at night explain

At night, when stomata close and transpiration stops, the water is held in the stem and leaf by the cohesion of water molecules to each other as well as the adhesion of water to the cell walls of the xylem vessels and tracheids. ... The cohesion-tension theory explains how water moves up through the xylem.
