|
Increases transpiration rate
|
|
|
Decreases transpiration rate
|
|
|
Either A or B
|
|
|
None of the above

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: -When the light intensity is higher, the stomata open wider to allow more carbon dioxide into the leaf for photosynthesis. This allows more water to be lost. Wind conditions cause the air movement around the plant to fluctuate.
