Question

What would happen to the transpiration on an extremely hot day?

Answer 1

Transpiration

1. Plants absorb a large quantity of water from the soil, but only a small quantity of it is utilized by the plant for biochemical processes, while most of the water is lost into the air from the leaves and other aerial parts of the plant, this loss of water in the form of vapors from the aerial parts of the plant is called transpiration.
2. The amount of water lost by transpiration is enormous, almost equal to 2-3 liters in sunflower plants, 35-45 liters in apples, and up to 1 tons per day in elm trees.

Transpiration on an extremely hot day

1. Transpiration helps in keeping the temperature of the plant on hot days; hence in order to maintain the plant’s temperature, the rate of transpiration increases.
2. The temperature of leaves would increase on extremely hot days, which will increase the rate of transpiration.
3. On hot summer days, the relative humidity decreases, which increases the rate of transpiration.
