Question

Which structure allow the flow of gases in and out of a leaf

Answer 1

Answer:

The correct answer is stomata.

Explanation:

The leaf structure is adapted for gas exchange between plants and the environment. The cells in the spongy mesophyll have tiny pores, termed as stomata, present in the leaf surface. Most of the stomata are found in the lower epidermis. These tiny pores control gas exchange. Opening and closing of stomata depend on the guard cell turgidity.

Diffusion of oxygen, carbon dioxide and water vapor in and out of the leaf is highest when these stomata are open.

Thus, the correct answer is stomata.

Answer 2
