Question

how is transpiration useful to plants?

Answer 1

Transpiration is the process through which excess water from plant body is released through the stomata present on surface of leaf.

Transpiration pull is the process through which water is taken into by the roots of the plant. It helps in maintaining cohesion-adhesion tension, so that water can move through xylem up to leaves.

It also helps in cooling process of the tree.

In a way transpiration helps in cloud formation. Water vapour released will help in cloud formation also.

Answer 2

hey mate here is your answer....

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.

hope it helps you....
