Options
- Acyanobacteria and phycobilisomes
- Bcyanobacteria and chromatophores
- Ccyanobacteria and heterocysts
- Darchaebacteria and heterocysts
Correct answer
B. cyanobacteria and chromatophores
Step-by-step solution
In some prokaryotes like cyanobacteria, there are other membranous extensions into the cytoplasm called chromatophores which contain pigments.
