Answer 1

Hey Friend, Here is your Answer...

This Process is known as Transpiration.
Presence of Small pores generally on the lower surface. Through these pores Carbon Dioxide enters the leaf. These pores are known as Stomata.
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 vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves.
During the process of transpiration, plants absorb water through their roots, and then distribute that water to their leaves by moving the water up through the stem, and then the leaves release that moisture by evaporation.

Ten per cent of all atmospheric moisture comes from plant transpiration with the remaining 90 per cent a result of evaporation of bodies of water such as oceans and lakes.
