Vedclass · Answer

(B) The rate of transpiration is influenced by several environmental factors such as light,temperature,humidity,and wind speed.$1$. Placing a plant in the dark closes the stomata,which decreases transpiration.$2$. Placing a plant in a cold room reduces the temperature,which decreases the rate of evaporation and thus transpiration.$3$. Placing a plant outside during rain increases humidity,which reduces the water potential gradient between the leaf and the atmosphere,thereby decreasing transpiration.$4$. Placing a plant in the draught of an electric fan increases the wind speed around the leaves. This removes the humid air layer (boundary layer) surrounding the leaf surface,thereby increasing the water potential gradient and significantly increasing the rate of transpiration.Therefore,option $B$ is the correct answer.

Which of the following would increase the rate of transpiration from the leaves of a potted plant?
