Detailed explanation-1: -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).

Detailed explanation-2: -Through photosynthesis, they use sunlight and carbon dioxide to make food, belching out the oxygen that we breathe as a byproduct. This evolutionary innovation is so central to plant identity that nearly all land plants use the same pores-called stomata-to take in carbon dioxide and release oxygen.

Detailed explanation-3: -Stomata are small pores present on the lower surface of green leaves of plants. They are responsible for the exchange of oxygen and carbon dioxide. Excess water is also removed from the plant through the stomata. This process is called transpiration.

Detailed explanation-4: -Stomata and Gas Exchange Stomata, as mentioned above, are the structures through which gas exchange occurs in leaves.

Detailed explanation-5: -The respiratory system works with the circulatory system to provide this oxygen and to remove the waste products of metabolism. It also helps to regulate pH of the blood. Respiration is the sequence of events that results in the exchange of oxygen and carbon dioxide between the atmosphere and the body cells.
