What is the role of transpiration in plants?

Transpiration is the process by which plants lose water in the form of water vapour from the surface of their leaves through small openings called stomata.

Transpiration plays several important roles in plants:

• It helps in cooling the plant during hot weather.
• It helps in the transport of water and minerals from roots to other parts of the plant.
• It maintains the water balance within the plant.

Thus, transpiration is essential for the proper growth and functioning of plants.
