Detailed explanation-1: -This is because plants perform both photosynthesis and cellular respiration. The process of photosynthesis requires carbon dioxide, water, and sunlight. Photosynthesis is necessary in order to produce food for the plant.

Detailed explanation-2: -Plants carry out both photosynthesis and cellular respiration. They make their own food, and then break down those glucose molecules later, generating ATP to power their cellular processes.

Detailed explanation-3: -Yes, like animals and humans, plants also breathe. Plants do require oxygen to respire, the process in return gives out carbon dioxide.

Detailed explanation-4: -Rather, plants use sunlight, water, and the gases in the air to make glucose, which is a form of sugar that plants need to survive. This process is called photosynthesis and is performed by all plants, algae, and even some microorganisms.
