PIGMENTS  

Definition

  • Pigments are light-absorbing molecules. In addition to chlorophyll, other pigments, principally yellow and orange carotenoids, as well as other forms of chlorophyll, are also present in green plants. These molecules absorb light and then pass the energy to the chlorophyll a. Accessory pigments, like the carotenoids, enable the plants to use more of the light than is trapped by chlorophyll a alone. (en)
