NEET BIOLOGY

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: -To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.

Detailed explanation-3: -Answer and Explanation: The reactants for photosynthesis are sunlight, carbon dioxide and water. Reactants are the materials that you start with in a chemical reaction and the products are what you make. During photosynthesis sunlight is used to excite the electrons in chlorophyll molecules during the light reactions.

Detailed explanation-4: -The reactants involved in the light reaction are NADP, ADP, and water molecules. After the completion of light reactions, the products obtained are the energy-rich molecules ATP NADPH, and oxygen, the last of which is already considered a by-product of photosynthesis.

Detailed explanation-5: -The photosynthesis chemical equation states that the reactants (carbon dioxide, water and sunlight), yield two products, glucose and oxygen gas. The single chemical equation represents the overall process of photosynthesis.
