Detailed explanation-1: -How is transpiration important to the plants? The process of transpiration keeps the cell turgid, cools the surface of the leaves, and helps in the movement of minerals from the soil to different parts of the plant.
Detailed explanation-2: -Transpiration helps in the cooling of leaf surfaces. Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapour and is released into the atmosphere.
Detailed explanation-3: -Transpiration is loss of water in the form of vapour through aerial parts of the plant. This creates a suction force that pulls water along with minerals from the roots to the leaf. When water evaporates through the plant, it absorbs heat, which in turn cools down the plant.
Detailed explanation-4: -Transpiration thus provides a significant cooling effect which keeps the plant from being over heated.
