Which process involves water loss from a plant's leaves through evaporation?

Explanation:
Transpiration is the process by which water exits a plant’s leaves as water vapor. When stomata—tiny openings on the leaf surface—are open to allow gas exchange for photosynthesis, water inside the leaf can evaporate and diffuse out into the air. This loss of water vapor from the leaves helps pull more water up from the roots through the plant’s xylem, driven by cohesion and tension in the water column. Condensation, precipitation, and infiltration refer to other parts of the water cycle and soil processes, not water loss from leaves as vapor.
