Detailed explanation-1: -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-2: -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. These sugar molecules contain the energy that living things need to survive.

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. That energy is then used to fix carbon dioxide into a three-carbon sugar.

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.
