Transpiration ?

Transpiration is the process by which plants lose water vapor through their leaves. It is a natural and necessary process for plants, as it helps in the absorption of water and nutrients from the soil, and also helps in the cooling of the plant. Transpiration occurs through small openings on the surface of leaves called stomata. These stomata open and close to regulate the amount of water vapor that is released. Transpiration is influenced by various factors such as temperature, humidity, wind, and the availability of water in the soil.
