Answer:
Photosynthesis is an endothermic reaction because sunlight energy is absorbed during the process of photosynthesis by the plants. Photosynthesis is the process through which plants convert light energy into chemical energy. Here is the chemical reaction involved: As we can see, water and carbon dioxide combine to form glucose and oxygen. Since new chemical species are formed, photosynthesis is clearly a chemical change.
