Which of the following are products of photosynthesis?

Photosynthesis is a crucial biological process by which plants, algae, and some microorganisms convert light energy into chemical energy, primarily in the form of glucose (sugar). During this process, carbon dioxide from the atmosphere and water from the soil are used as raw materials, and the end products are oxygen and glucose.

In this context, the correct answer identifies oxygen and sugar as key products of photosynthesis. Oxygen is released as a byproduct into the atmosphere, which is essential for the respiration of most living organisms. The sugar produced serves as an energy source that can be utilized for growth, reproduction, and various metabolic activities in the plant.

Other choices, such as light and heat, do not represent products of photosynthesis; instead, they are conditions necessary for the process to occur. Similarly, while water is involved in photosynthesis, it is not produced by this process but rather consumed. Carbon dioxide is also a reactant rather than a product. This highlights the specific role of oxygen and sugar in photosynthesis, further emphasizing their importance in the broader ecological context.
