List any four advantages of transpiration to the plant.

Four advantages of transpiration to the plants are:

1. It has a cooling effect on leaf surface. This cooling effect helps the plant withstand the heat. Intense heat can destroy the enzymes.
2. It maintains the suction force due to transpirational pull and thus maintains ascent of sap.
3. Regular ascent of sap results in proper absorption and distribution of water and minerals.
4. Transpiration also maintains the turgidity of plant cells.
