Question

Why are there more chloroplasts below the leaf?

Answer 1

Dear Student,

The question should have been stomata are more on the lower side of the leaf. why?

Stomata are more numerous on the lower side of the leaf to prevent transpiration. Transpiration is the loss of water through stomata, so, more stomata are found on the lower surface to prevent excessive loss of water. As the lower surface of leaf is not directly exposed to sun, rate is transpiration is low from the lower surface.
