LIFE SCIENCE

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: -Carbon dioxide and water are used as raw materials during photosynthesis to manufacture complex carbohydrates such as sugars and in most of the cases, oxygen is released as a waste product. Hence, the process of photosynthesis involves the intake of carbon dioxide and the release of oxygen.

Detailed explanation-3: -Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.
