The chemical process by which plants use carbon dioxide and water to produce glucose is known as photosynthesis. This process primarily occurs in the chloroplasts of plant cells, utilizing sunlight as an energy source. The overall equation can be simplified to: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2. In this process, carbon dioxide is fixed into an organic compound, which is then converted into glucose, a form of energy storage for the plant. Oxygen is released as a byproduct.
