Which of the following are products of photosynthesis?

Photosynthesis is a biological process carried out primarily by plants, algae, and some bacteria, in which sunlight is converted into chemical energy. The process takes place in the chloroplasts and involves two main stages: the light-dependent reactions and the light-independent reactions (Calvin cycle).

The primary products of photosynthesis are glucose (sugar) and oxygen. During this process, carbon dioxide from the atmosphere and water absorbed by the roots are used in the presence of light energy to produce glucose, which serves as an energy source for the plant. Oxygen, a byproduct of this process, is released into the atmosphere, contributing to the breathable air we rely on.

Therefore, the correct answer highlights the production of both oxygen and sugar, aligning with our understanding of photosynthesis as a means through which plants not only create their own food but also generate oxygen essential for life on Earth. This is foundational knowledge in environmental science, as it emphasizes the role of plants in ecosystems and their importance in the carbon and oxygen cycles.

While other options present elements related to photosynthesis, they do not reflect the main outputs of the process itself. For instance, light and heat are involved as energy sources but are not products of photosynthesis. Water and oxygen could be
