In the reaction of photosynthesis carbon dioxide and oxygen to form glucose.
photosynthesis, is the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and is used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds such as glucose.
It would be impossible for us to overestimate the importance of photosynthesis in the maintenance of life on Earth. If photosynthesis stops, there would soon be little food or other organic matter on Earth. Most organisms would disappear, and in time Earth’s atmosphere and would become nearly devoid of gaseous oxygen
Hence the reaction for photosynthesis is as follows;
