Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Plants breathe in ____ ?
A
Carbon dioxide
B
Oxygen
C
Helium
D
Air
Explanation: 

Detailed explanation-1: -So they take in what you exhaled, they take in carbon dioxide and they give out oxygen. And this is during the day. So during the day they take in carbon dioxide and they release oxygen. And in the night, they behave almost like us.

Detailed explanation-2: -Photosynthesis is the process by which plants use energy from the sun to make food. They use carbon dioxide from the air and water from the soil to make sugar and oxygen. Most plants release oxygen only during the day, when the sun can power photosynthesis.

Detailed explanation-3: -During daylight hours, plants take in carbon dioxide and release oxygen through photosynthesis, and at night only about half that carbon is then released through respiration.

Detailed explanation-4: -Plants need both carbon dioxide and oxygen for survival.

Detailed explanation-5: -Typically, stomata are open during the day and closed at night, like some people’s mouths. Many other signals cause stomata to open and close. Open stomata allow carbon dioxide to enter the plant, however, water vapour can escape, so regulation of stomata is crucial for maintaining plant water status.
