Detailed explanation-1: -The reactants of photosynthesis are carbon dioxide and water. We’ve established that plants need carbon dioxide (CO2) and water (H2O) to produce their food, but where do these reactants come from and how do they get where they need to go inside the plant?

Detailed explanation-2: -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-3: -The reactants for photosynthesis are sunlight, water and carbon dioxide. During photosynthesis the energy in sunlight is harvested by chlorophyll to produce chemical energy and electron carriers for the other steps.

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.
