It increases
|
|
|
It stays the same
|
|
|
It decreases
|
|
|
None of the above

Explanation:
Detailed explanation-1: -The transpiration rate is increased due to the increase in light intensity. During daytime in the sunlight, the rate of transpiration is faster.
Detailed explanation-2: -Transpiration is affected by air movement. As the movement of air increases, the concentration gradient is increased, so the rate of transpiration increases. Transpiration is affected by light intensity. As the light intensity decreases, the stomata close up and there is a reduction in photosynthesis.
