Chlorophyll is a green pigment found in plants. It plays a crucial role in the process of photosynthesis, allowing plants to absorb sunlight and convert it into energy. Chlorophyll mainly resides in the chloroplasts of plant cells and is responsible for the characteristic green color of leaves. This pigment captures light energy, primarily from the blue and red wavelengths of sunlight, while reflecting green light, which is why plants appear green to our eyes. The effectiveness of chlorophyll in capturing solar energy is vital for sustaining life on Earth by facilitating the production of oxygen and organic matter.
