Question
[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
|
Increased environmental temperature results in increased rate of transpiration because of ____
|
|
increased kinetic energy of the water molecules in the leaf xylem
|
|
|
increased evaporation of water from the substomatal air spaces
|
|
|
increased diffusion of water vapour from the surfaces of the mesophyl cells
|
|
|
increased evaporation of water from the surfaces of the mesophyl cells
|
Explanation:
Detailed explanation-1: -Higher temperatures mean water molecules evaporate at a faster rate which increases the rate of transpiration.
Detailed explanation-2: -Transpiration increases with increasing air temperature and wind velocity. At constant temperature and wind velocity, transpiration rate is governed by moisture content of air. Transpiration also increases with decreasing relative humidty at constant wind velocity.
Detailed explanation-3: -As temperature increases, the rate of transpiration increases because water molecules diffuse from the leaf faster.
Detailed explanation-4: -The wider the leaf area, the greater the rate of transpiration because wide leaves tend to have more stomata [5].
