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: -Photosynthesis is the process by which green plants synthesise their own food from carbon dioxide and water in the presence of sunlight and chlorophyll. During this process, oxygen is released as a by-product.

Detailed explanation-3: -When green plants perform photosynthesis, they take in carbon dioxide and release oxygen into the air.

Detailed explanation-4: -The oxygen released during photosynthesis is from the water. The plants will absorb water as well as carbon dioxide during photosynthesis. Later these water molecules are converted into oxygen and sugar.
