What is the formula for photosynthesis?

The formula for photosynthesis is represented by the correct answer, which describes the process where carbon dioxide and water, in the presence of light energy, are converted into glucose and oxygen. Specifically, the reaction illustrates that six molecules of carbon dioxide (6CO₂) combine with six molecules of water (6H₂O) and light energy to produce one molecule of glucose (C₆H₁₂O₆) and six molecules of oxygen (6O₂).

This equation encapsulates the essence of photosynthesis, which occurs primarily in the chloroplasts of plant cells. The importance of light energy is also highlighted, as it powers the reactions, allowing plants to convert inorganic molecules into organic compounds, which are crucial for life on Earth.

Other options do not accurately represent the photosynthesis process; for instance, some inaccurately place oxygen as a reactant or product in contexts that do not align with the established chemical understanding of photosynthesis. The provided equation reflects the correct stoichiometry and serves as a foundation for understanding how plants synthesize food, contributing to the broader ecological and biochemical cycles.
