Transpiration is (mainly) the process of losing excess water by plants through small pores present on leaves surface known as stomata.

Explanation:

Transpiration is the loss of water from a plant in the form of water vapor. Water is absorbed by roots from the soil and transported as a liquid to the leaves via xylem. In the leaves, small pores allow water to escape as a vapor. Of all the water absorbed by plants, less than 5% remains in the plant for growth.
