NEET BIOLOGY

Detailed explanation-1: -During the day, there is a higher requirement of carbon dioxide as it is the reagent used for photosynthesis giving out oxygen as the product. This is why plants release oxygen during the day when photosynthesis occurs as the production exceeds the amount of oxygen required by respiration.

Detailed explanation-2: -Photosynthesis is the process by which plants use energy from the sun to make food. They use carbon dioxide from the air and water from the soil to make sugar and oxygen. Most plants release oxygen only during the day, when the sun can power photosynthesis.

Detailed explanation-3: -Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Detailed explanation-4: -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-5: -Plants release oxygen during the day in the presence of natural light through the process of photosynthesis. While at night, the plants uptake oxygen and release carbon dioxide, which is called respiration.
