Detailed explanation-1: -Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose.

Detailed explanation-2: -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-3: -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-4: -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.
