Photosynthesis can be best described by option C, or “the process plants use to make food by using sunlight to turn carbon dioxide and water into glucose [and oxygen].”
In photosynthesis, plants use the reactants sunlight, carbon dioxide, and water to create the products glucose and oxygen. This is displayed in its chemical equation:
sunlight + CO2 + H2O —> C6H12O6 + O2
Plants use photosynthesis to create food; the food created is then transformed into energy (ATP) for humans through a process called cellular respiration.
