Detailed explanation-1: -Plants carry out photosynthesis only during the day and respiration only at night.
Detailed explanation-2: -(ii) Plants carry out photosynthesis only during the day and respiration only at night.
Detailed explanation-3: -During the day, photosynthesis is dominant, so there is a net release of oxygen. At night, photosynthesis stops but respiration continues, so there is a net consumption of oxygen.
Detailed explanation-4: -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-5: -If a plant is releasing carbon dioxide and taking in oxygen during the day, This means that there is no photosynthesis occurring during the day time.
