Detailed explanation-1: -Plants, like animals, take in oxygen and give out carbon dioxide during respiration.

Detailed explanation-2: -Plants need to breathe for the same reason people and animals must breathe – they need oxygen to convert food into energy. The relationship between air and indoor plants is crucial to keeping your plants looking their best.

Detailed explanation-3: -Hint There are different type of cells present, it may be aerobic, the cells which require oxygen for producing the energy and for their survival, whereas the other one is called anaerobic, which do not require oxygen for the survival and producing the energy.

Detailed explanation-4: -Once they have water and carbon dioxide, they can use energy from sunlight to make their food. The leftovers from making the plant food is another gas called oxygen. This oxygen is released from the leaves into the air.

Detailed explanation-5: -Through a process called photosynthesis, leaves pull in carbon dioxide and water and use the energy of the sun to convert this into chemical compounds such as sugars that feed the tree. But as a by-product of that chemical reaction oxygen is produced and released by the tree.
