Cyanobacteria and some other photosynthetic bacteria do not have chloroplasts. How do they conduct photosynthesis ?

Text Solution

Verified by Experts

In Cyanobacteria, the peripheral cytoplasm contains the photosynthetic apparatus. Flattened membrane vesicles called thylakoids house the pigments and proteins that make up photosynthetic machinery. Each thylakoid is studded with phycobillisomes (Chlorophyll a) and accessory pigments (phycobilliproteins) trap photons is used in photosynthesis.
