List its two-

functions.​

Answer 1

the process of water passing out from the surface of a plant or leaf is known as transpiration.

Answer 2

The water, warmed by the sun, turns into vapor (evaporates), and passes out through thousands of tiny pores (stomata) mostly on the underside of the leaf surface. This is transpiration. It has two main functions: cooling the plant and pumping water and minerals to the leaves for photosynthesis.
