The process by which water evaporates from plants is called "transpiration." During transpiration, plants absorb water through their roots, which then travels through the plant and eventually evaporates into the atmosphere from tiny openings in the leaves known as stomata. This process is crucial for maintaining the water cycle as well as regulating the plant's temperature. Transpiration also helps in nutrient uptake as it creates a vacuum that draws water and minerals upward from the roots. Overall, this natural process supports plant health and contributes significantly to the ecosystem by releasing moisture into the air.
