Which of the following is not an accessory pigment?
1 Carotenes
2 Phycobilin
3 Chlorophyll-b
4 Chlorophyll-a
Explanation:
Phycobilins are light-capturing pigments found in cyanobacteria. Chlorophyll-a is the chief pigment in autotrophic organisms. Xanthophylls, chlorophyll-b and carotenoids are all accessory pigments.
