The two gases that plants exchange are
A
nitrogen and oxygen
B
carbon dioxide and nitrogen
C
oxygen and carbon dioxide
D
none of these
Explanation: 

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). Normally stomata open when the light strikes the leaf in the morning and close during the night.

Detailed explanation-2: -Leaves of plants have tiny pores called stomata, which is used for the exchange of gases. The oxygen, taken in through stomata is used by the cells in the leaves to break down glucose into carbon dioxide and water.

Detailed explanation-3: -Stomata. 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: -At each cell in your body, oxygen is exchanged for a waste gas called carbon dioxide. Your bloodstream then carries this waste gas back to the lungs where it is removed from the bloodstream and then exhaled. Your lungs and respiratory system automatically perform this vital process, called gas exchange.
