Chlorophyll, the green pigment in plants, plays a crucial role in photosynthesis by capturing sunlight, but the essential chemical element necessary for this process is carbon (C). It combines with water (H2O) absorbed by the roots to produce glucose (C6H12O6) and oxygen (O2). During photosynthesis, plants take in carbon dioxide (CO2) from the atmosphere, which is then utilized in the conversion of light energy into chemical energy, fueling growth and the production of energy-rich compounds essential for life on Earth.
