Why is transpiration important for plants?

Transpiration is the process of water evaporating from plant leaves' stomata. Through stomatal holes, extra water is expelled from the plant's leaves.

Similar to the vacuum or suction formed when drinking liquid using a straw, transpiration creates a pull or vacuum inside the vessels. A transpiration pull is a term for such a suction.

It permits the xylem to move water from the plant's roots to its leaves, defying gravity.

Advantages of transpiration are as follows:

1.    Transpiration helps in the gaseous exchange.

2.    It helps to remove the excess water absorbed by plants.

3.    It helps in the absorption and distribution of water as well as mineral salts in plants.

4.    It provides coolness to the plant body.

5.    It maintains the osmotic balance of the plant cells.
