Explain the significance of transpiration. 

Significance of Transpiration :
1. Maintaining a cooling effect by taking up the heat of the plant and converting the water to water vapour which is given off during transpiration.
2. Maintaining optimum Turgor pressure as plant absorb excess amount of water which is released during termination hence maintaining an optimum amount of Turgor pressure for healthy and normal growth.
3. Helps in the transportation of minerals which are absorbed by the roots from the soil by creating a transpiration pull and hence helping in proper distribution of minerals.
4. Helping in water transport by creating a transpiration pull and hence maintaining a continuous water supply to the top.
