Question

Photosynthetic bacteria include

• A. Nitrobacter and Nitrosomonas
• B. Chlorobium and Rhodospirillum
• C. Streptococcus and Staphylococcus
• D. Chlorobium and Clostridium

Answer 1

The correct option is B Chlorobium and Rhodospirillum

Photosynthetic bacteria are those bacteria which are capable of producing energy from the sunlight in a similar way as plants do. However, instead of chlorophyll, they have bacteriochlorophyll to capture sunlight. Examples include purple bacteria, green sulfur bacteria (Chlorobium), Cyanobacteria, anaerobic Rhodospirillum rubrum.

Thus, the correct answer is 'Chlorobium and Rhodospirillum.'
