Photosynthesis is the process by which green plants, algae, and some bacteria use sunlight to convert CO₂ from the air and H₂O from the soil into glucose (a form of sugar used for energy) and O₂ (released into the atmosphere). Chlorophyll in the chloroplasts captures light energy to drive the reaction.Overall equation:6CO_2 + 6H_2O + \text{light energy} \xrightarrow{\text{chlorophyll}} C_6H_{12}O_6 + 6O_2This process stores energy from sunlight in the chemical bonds of glucose.
