Answer 1

Answer:

TO PREVENT EXCESSIVE LOSS OF WATER THROUGH TRANSPIRATION

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.
