Solution(By Examveda Team)

The rate of transpiration is related to Light, temperature, atmospheric humidity and wind.
Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers.
The rate of transpiration is controlled by the stomatal aperture, and these small pores open especially for photosynthesis, a light supply will encourage open stomata.
Temperature affects the rate of transpiration in two ways, an increased rate of evaporation due to a temperature rise will hasten the loss of water.
Relative humidity affects drier surroundings giving a steeper water potential gradient, and so increasing the rate of transpiration.
In still air, water lost due to transpiration can accumulate in the form of vapour close to the leaf surface. This will reduce the rate of water loss, as the water potential gradient from inside to outside of the leaf is then slightly less.
