What Is the Relationship Between Pigments and Chlorophyll?

Chlorophyll is a pigment, or a material that absorbs certain wavelengths of light. Plants use chlorophyll's ability to absorb light in photosynthesis, notes Scienceline.

Chlorophyll is particularly good at absorbing blue and red light, but it has almost no ability to absorb green light. White light contains all the colors of the spectrum, so when the sun's rays hit a plant, the chlorophyll absorbs the other colors but reflects the green, giving the plant its color. The plant can then use the absorbed light in photosynthesis.

While chlorophyll is the most easily observed pigment in plants, there are others, notes Scienceline. Charotenoids, for instance, are visible in plants during fall when they reduce the amount of chlorophyll in their leaves.
