Answer
The two main advantages of transpiration to green plants are as follow:
- Cooling effect — The water keeps on evaporating from the leaf surface during transpiration. The heat required for evaporation of water is obtained from the plant itself and thus, the plant cools itself when it is in hot environment.
- Transpirational pull — The roots of the plant pull up more water from the soil to make up for the water loss during transpiration. As a result, important mineral salts, which is essential for the plant growth, are also brought along with the water from the soil.
