Photosynthesis is the process by which plants and other organisms (i.e. cyanobacteria and algae) convert light energy from the sun into chemical energy. In the process of photosynthesis, carbon dioxide (CO2) and water (H2O) undergo a series of chemical reactions initiated by light energy to produce glucose (C6H12O6) and oxygen gas (O2). As sunlight shines down on plants, water is absorbed by the root system of the plant.
