Transpiration

Transpiration is an important process in the water cycle and is driven by the absorption of sunlight. It occurs when water is taken from the soil and evaporated from the leaves of plants. The water is drawn up from the roots of the plant, and then released through the stomata - the tiny pores on the surface of the leaves. This process is driven by the energy of the sun, which heats the water and causes it to evaporate. As the water evaporates, it cools the surrounding air and helps keep the plant cooler than its surroundings. Transpiration is necessary for the plant to take in carbon dioxide, which is then used to produce food in the form of sugars through photosynthesis. Transpiration also helps to maintain the balance of water in the environment by allowing water to be recycled and returned to the atmosphere. Without transpiration, the soil would become dry and the plant would not be able to grow.
