Detailed explanation-1: -Leaves consist of tiny pores known as stomata. Gaseous exchange occurs through diffusion via stomata. Guard cells regulate each of the stomata. Exchange of gases occurs with the closing and opening of the stoma between the inferior of leaves and the atmosphere.

Detailed explanation-2: -The exchange of oxygen and carbon dioxide in the leaf (as well as the loss of water vapor in transpiration) occurs through pores called stomata (singular = stoma). Normally stomata open when the light strikes the leaf in the morning and close during the night.

Detailed explanation-3: -Gas exchange in plants is achieved by stomata and lenticels. The epidermis has tiny pores called stomata (singular, stoma) that control transpiration and gas exchange with the air. During the day when photosynthesis occurs, the oxygen released from the process is utilized for respiration.

Detailed explanation-4: -Photosynthesis is a key biological process that involves the exchange of CO2 and O2 between the atmosphere and plant leaves via pores in the leaves called stomata.
