Evaporation of water at the stomata followed by its diffusion through mesophyll cells

Detailed explanation-1: -Transpiration is the evaporation of water from plants occurring at the leaves while their stomata are open for the passage of CO2 and O2 during photosynthesis.
Detailed explanation-2: -Transpiration is the evaporation of water through the stomata, cuticle and lenticels of a plant.
Detailed explanation-3: -Transpiration is the loss of water from the plant through evaporation at the leaf surface. It is the main driver of water movement in the xylem.
Detailed explanation-4: -When the plant opens its stomata to let in carbon dioxide, water on the surface of the cells of the spongy mesophyll and palisade mesophyll evaporates and diffuses out of the leaf. This process is called transpiration .
Detailed explanation-5: -: the act or process or an instance of transpiring. especially : the passage of watery vapor from a living body (as of a plant) through a membrane or pores.
