Shanu told his father that plants exude out a lot of water in vapour form from leaves define the process what is its importance how do stomata help in this process

Transpiration is the process by which plants lose water in the vapor form, from the aerial parts of the plant.
It is a necessary process, because

• It helps to remove excess water.
• It provides a cooling effect at higher temperature.
• It helps to absorb and distribute the salts.
• It helps for the upward movement of cell sap through the xylem.

The water from the soil is transported to all parts of the plant with the help of force generated by transpiration and excess water is lost from the stomata.
