High light intensity favours high rate of transpiration because ____

|
high light intensity favour high rate of evaporation
|
|
|
high light intensity favours high rate of diffusion
|
|
|
high light intensity favours high rate of photosynthesis
|
|
|
high light intensity favours high rate of chlorophyl activation
|
Explanation:
Detailed explanation-1: -Light intensity: The transpiration rate is increased due to the increase in light intensity. During daytime in the sunlight, the rate of transpiration is faster. This is because the stomata remains open to allow the inward diffusion of carbon dioxide for photosynthesis.
Detailed explanation-2: -The rate of transpiration decreases with decrease in temperature and decrease in light intensity.
Detailed explanation-3: -Transpiration is affected by light intensity. As the light intensity decreases, the stomata close up and there is a reduction in photosynthesis. This means that very little water can escape and so the rate of transpiration decreases.
