Explanation:
Detailed explanation-1: -The properties of cohesion and adhesion are closely related to transpiration. As water moves out of the leaves of a plant due to transpiration, more water is drawn upward inside the plant to replace the water that has evaporated. The movement of water inside vessels of the plant occurs due to cohesion and adhesion.
Detailed explanation-2: -Transpiration draws water from the leaf. The water leaves the tube-shaped xylem and enters the air space between mesophyll cells. Finally, it exits through the stoma. Cohesion and adhesion draw water up the xylem.
