What is the natural compound present in green plants that gives them their colour?

The natural compound present in green plants that gives them their color is chlorophyll. Chlorophyll is crucial for photosynthesis, the process by which plants convert sunlight into energy. It absorbs light most efficiently in the blue and red parts of the spectrum but reflects green light, which is why plants appear green to us. This pigment is found in the chloroplasts of plant cells and is essential for the synthesis of organic compounds that sustain plant life.
