Detailed explanation-1: -Thus, the correct answer is (C). Carbon dioxide enters the leaves through tiny pores present on the surface of the leaves called stomata.

Detailed explanation-2: -Carbon dioxide It moves by diffusion through small holes in the underside of the leaf called stomata. Guard cells control the size of the stomata so that the leaf does not lose too much water in hot, windy or dry conditions. The lower part of the leaf is a spongy layer with loose-fitting cells.

Detailed explanation-3: -∙ On the underside of leaves, there are small openings called stomata. It is from here that carbon dioxide enters the plant.

Detailed explanation-4: -Carbon dioxide from the air enters the leaf through the stomata.

Detailed explanation-5: -Carbon dioxide is a gas found in the air; plants can take in this gas through tiny holes in their leaves. Once they have water and carbon dioxide, they can use energy from sunlight to make their food.
