Detailed explanation-1: -The loss of water in the form of vapour from the aerial parts of the plant is known as transpiration. The transpiration in plants will be lowest when there is high humidity in the atmosphere.
Detailed explanation-2: -As the relative humidity of the air surrounding the plant rises the transpiration rate decreases. It is easier for water to evaporate into dryer air than into more saturated air.
Detailed explanation-3: -To save water in desert plants, transpiration takes place at night and rate of transpiration is low when compared to water and forest plants. Option B is correct. Was this answer helpful?
Detailed explanation-4: -The transpiration rate is inversely proportional to the humidity in air. High humidity reduces the outward diffusion of water through the stomata. As a result, less water is lost, and lower transpiration rates are observed.
