Question

Transpiration allows plants to lose excess water. It also has two other functions. What are these?

Answer 1

In addition to allowing plants to lose excess water, transpiration performs following functions:

1. The water lost through transpiration creates a suction force, which helps in the absorption of mineral salts and water through the roots of the plants.

2. Transpiration also produces a cooling effect which helps in regulating the temperature of the plant.
