Question

The stomata present in the leaves help in _______.

• A. Intake of CO${}_2$ during photosynthesis
• B. Release of O${}_2$ during photosynthesis
• C. Release of water vapour during transpiration
• D. All of these

Answer 1

The correct option is D All of these

Stomata are minute openings found in the epidermis of leaves and stems. Stomata allow gases such as carbon dioxide, water vapour, and oxygen to diffuse into and out of the internal tissues of the plant.

Transpiration is the process by which plants lose excess water in the form of water vapour, through stomata. During photosynthesis, plants take in carbon dioxide from the air and release oxygen as a byproduct, through the stomata.

So, the correct answer is option D.
