Transpiration is a very important term in a botany. Transpiration is the process of water movement through a plant and it evaporation from aerial parts such as stems, flowers and leaves.
We Know that water is very essential for plants it helps to plants for growth but only small amount of water taken up by the roots is used for growth and metabolism. The remaining water is lost by transpiration.
In the process of transpiration water molecules in the plant tissue are removed from the aerial parts of the plants.
There are three types of transpiration in plant.
1) Stomatal transpiration
2) Lenticular transpiration
3) Cuticular transpiration
● Importance of Transpiration
1) Transpiration helps to maintain osmosis and keeps the cells rigid.
2) It helps in the absorption of carbon dioxide from the atmosphere throughout photosynthesis as the opening of stomata in day time help gaseous exchange.
3) Transpiration provide water for Photosynthesis.
4) Transpiration also maintains the turgidity of the cell and helps in cell division.
5) Transpiration helps for the exchange of gases and it’s also provided coolness to the plant body.
