It doesn’t impact the rate of transpiration

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: -[D] As light intensity decreases, the rate of transpiration increases because stomata are open in the light.
Detailed explanation-3: -Plants transpire more rapidly in the light than in the dark. This is largely because light stimulates the opening of the stomata (a mechanism). Light also speeds up transpiration by warming the leaf. Plants transpire more rapidly at higher temperatures because water evaporates more rapidly as the temperature rises.
