During the day, when stomata are open and transpiration rates are high, the primary driving force for water movement in the xylem is transpiration pull. This process relies on the cohesive and adhesive properties of water molecules to create tension, ...

Root pressure contributes to water transport in plants, particularly during the night when transpiration rates are low. It involves the active pumping of water into the xylem by root cells, creating pressure that pushes water upward.

Transpiration helps regulate plant temperature by evaporating water from the leaf surfaces. This evaporative cooling process reduces leaf temperature and helps prevent overheating, particularly in hot environments.

Transpiration is the loss of water vapor from the aerial parts of a plant, primarily through stomata. It creates a suction force that pulls water from the xylem vessels in the roots to the leaves, aiding in water absorption and ...
