Which of the following is a product of photosynthesis?

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy stored in glucose, a type of sugar. During this process, plants take in carbon dioxide from the atmosphere and absorb water from the soil. Through a series of chemical reactions powered by sunlight, these components are transformed into glucose and oxygen. The glucose produced serves as an essential energy source for the plant, fueling its growth, development, and cellular processes.

In contrast, carbon dioxide and water are reactants used in photosynthesis, rather than products. Nitrogen is also not involved in the process of photosynthesis, as it is primarily used by plants for building amino acids and proteins, but it does not play a direct role in the synthesis of glucose. Thus, the accurate answer is glucose, as it is the primary product of photosynthesis, indicating that energy from sunlight has been converted into a usable form for the plant.
