Chlorophyll a is the primary light-absorbing pigment in plant leaves. It absorbs light wavelengths in the red and blue range, and reflects back green waves, which gives most leaves their distinctive green color. Different accessory pigments absorb different wavelengths of light.
Carotenoids, the most common accessory pigments, absorb extra blue wavelengths. Inheritance 5. Genetic Modification 4: Ecology 1. Energy Flow 3. Carbon Cycling 4. Climate Change 5: Evolution 1.
