Quizplus · Accepted Answer

Transpiration is the loss of water vapor from plant surfaces, mainly through stomata. This process is driven by a gradient of water potential, which is created by a combination of factors, including the evaporation of water from the stomata (creating a low water potential in the surrounding air), and the resistance to water movement through the plant (due to the cohesive and adhesive properties of water, and the presence of openings in the xylem). Overall, the water potential in the leaf is much more negative than that in the atmosphere, which drives the movement of water out of the leaf and into the air.
