Detailed explanation-1: -The correct answer is utilization of oxygen. Explanation: Photosynthesis is the process by which plants produce oxygen by combining sunlight, carbon dioxide, and water. Thus, in the photosynthesis process utilization of oxygen does not occur.
Detailed explanation-2: -Carbon dioxide (CO2) is a product of respiration and not photosynthesis. The CO2 released in the air is then absorbed or fixed by plants during photosynthesis. Hence this option is correct.
Detailed explanation-3: -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.
