A) fucoxanthin
B) chl-b
C) anthocyanin
D) phycocyanin
Correct Answer: D
Solution :
Cyanobacteria has a group of ancient Gram-negative, photosynthetic prokaryotes. Many botanists prefer cyanobacteria as a blue-green algae. The photosynthetic pigments present in the cell are chlorophyll,\[\text{ }\!\!\alpha\!\!\text{ ,}\,\,\text{ }\!\!\beta\!\!\text{ }\] carotene, myxoxantho phyll, myxoxanthin, C-phycocyanin and C-phycoerythrin. The C-phycocyanin is blue and C-phycoerythrin is red in colour. If C-phycocyanin is more as compared to C-phycoerythrin, it gives characteristic blue-green colour to the algae.
