The primary function of chlorophyll is to absorb light energy for photosynthesis, the process by which green plants convert light energy into chemical energy. Chlorophyll primarily absorbs light in the blue and red wavelengths while reflecting green, which is why plants appear green. This pigment is located in the chloroplasts of plant cells and plays a critical role in converting carbon dioxide and water into glucose and oxygen using sunlight. The glucose produced provides energy for the plant's growth and metabolic processes, while the oxygen released is essential for the respiration of most living organisms.
