BOTANY

Detailed explanation-1: -Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

Detailed explanation-2: -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-3: -Plants produce oxygen as a waste product of making sugar using sunlight, carbon dioxide, and water. If a plant needs energy, but doesn’t have sunlight, then it can burn the sugar that it made back when it had sunlight, and doing so requires oxygen.

Detailed explanation-4: -Final answer: During photosynthesis, plants take in carbon dioxide and release oxygen.

Detailed explanation-5: -Photosynthesis: Plants release oxygen during the day in the presence of sunlight through the process of photosynthesis. It is the process in which plants take up carbon dioxide and water, and in the presence of sunlight and chlorophyll, produce glucose and oxygen.
