Photosynthesis is a chemical change process. It can be summarized in a single chemical equation, but that equation is actually the sum total of a collection of chemical reactions.
Beside this, what are the two chemical reactions in photosynthesis?
Light-dependent and light-independent reactions are two successive reactions that occur during photosynthesis.
Simply so, why is photosynthesis an example of chemical reaction? Photosynthesis requires energy, making it an endothermic reaction. Light, generally sunlight, is the source of this energy. The process converts the sun’s electromagnetic energy into chemical energy, which is then stored in chemical bonds in the plant.
