Answer 1

Water moves from the soil into plant roots, up through the sapwood into the leaves. 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 process is transpiration. It has two main functions: cooling the plant and pumping water and minerals to the leaves for photosynthesis. Photosynthesis, respiration and translocation can not keep the plant cool
