Detailed explanation-1: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. 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.

Detailed explanation-2: -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.

Detailed explanation-3: -Final answer: As a result, by-product of photosynthesis is oxygen.

Detailed explanation-4: -In photosynthesis, solar energy is harvested and converted to chemical energy in the form of glucose using water and carbon dioxide. Oxygen is released as a byproduct.

Detailed explanation-5: -Chlorophyll uses sunlight energy to transform the carbon dioxide and water into oxygen and carbon-based compounds such as glucose, a sugar that helps plants grow. In the process, the plant or tree produces excess oxygen, which it releases into the atmosphere.
