DENDROLOGY

Detailed explanation-1: -Explanation: Light dependent reactions convert solar energy to chemical energy (in the form of ATP and NADPH ). Sunlight and H2O are the reactant of the light dependent reaction.

Detailed explanation-2: -In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and that energy is converted into stored chemical energy. In the light-independent reactions, the chemical energy harvested during the light-dependent reactions drives the assembly of sugar molecules from carbon dioxide.

Detailed explanation-3: -The reactants of photosynthesis are carbon dioxide and water. These are the molecules necessary to begin the process. But one more item is necessary, and that is sunlight. All three components, carbon dioxide, water, and the sun’s energy are necessary for photosynthesis to occur.
