Answer:
Plants exchange oxygen and carbon dioxide. The oxygen is used for respiration and is also a waste product of photsynthesis. The carbon dioxide is used for photsynthesis.
During the day time, the stomata of the plant will open to let the carbon dioxide in for photsynthesis. Cabron dioxide diffuses into the leaf down a concetration gradient. oxygen will leave the leaf down the concentration gradient.
This process is the gas exchnage of plants.
How stomata open: Stomata open during the dayby absorbing water vapor, become turgid and and open. During the night, the stomata becomes flaccid and floppy. this causes it to close.
