NEET BIOLOGY

Detailed explanation-1: -Stomata are the tiny pores located on the epidermis of leaves, stems and other organs. During cellular respiration, stomata facilitate gaseous exchange by opening and closing of the pores.

Detailed explanation-2: -Although the surface of a leaf may look smooth, it is lined with tiny openings called stomata. When stomata are open, water vapor and other gases, such as oxygen, are released into the atmosphere through them.

Detailed explanation-3: -Its prime function is to exchange the gases by closing and opening the pores in the leaves. It assists in eradicating excess water from the leaves. It removes oxygen and takes in carbon dioxide at the time of photosynthesis. It assists in monitoring the movement of water via transpiration.

Detailed explanation-4: -The leaves of plants have tiny pores on their surface which are called stomata. The exchange of gases in the leaves during respiration takes place through stomata. This happens as follows: Oxygen from the air enters into a leaf through stomata and reaches all the cells by the process of diffusion.

Detailed explanation-5: -Stomata provide for gas exchange and transpiration. Two guard cells that control the opening and shutting of the stomata surround it. For gaseous exchange and to release water vapor during transpiration, stomata open during the day. The change in the guard cell’s turgor pressure causes the stomata to open and close.
