Chlorophyll ‘a’ is the primary pigment for light reaction. What are accessory pigments? What is their role in photosynthesis?
Accessory pigments are known to support chlorophyll in the trapping of solar radiation. The accessory pigments are chlorophyll b, xanthophylls and carotenoids. They help collect and transfer solar radiation to chlorophyll a. In light harvesting, accessory pigment thus has a supporting role.
