Does transpiration serve any useful function in the plants? Explain.
The process of Transpiration is the loss of water from leaves that serves very useful function in the plants because it generates s ‘suction force’ in xylem which can pull water from the roots up to great height in the tall trees which is known as ascent of sap.
Another function of transpiration is that it keeps the plant cool in higher temperature by the evaporation. The rate of transpiration increase in moving air because this carries away water vapour from leaves as fast as it comes out of stomata. Higher vapour pressure differences between leaf air spaces and the external air increases the transpiration rate. And, when the rate of transpiration increases, the rate of absorption of water through the roots also get increased. Thus, by keeping a plant under the fan, water absorption through roots can be increased.
