What is the effect of less sun on transpiration?
A
Speeds it up
B
Slows it down

Detailed explanation-1: -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. During dark, the stomata are closed, and hence transpiration hardly occurs at night.

Detailed explanation-2: -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-3: -Light is the primary driving factor for transpiration in plants.
