Kingdom Monera
Mediumbiology
Which characteristic is typical of cyanobacteria but absent in most true bacteria?
Select the correct option:
Solution
Incorrect! Answer:
Photosynthetic pigments with oxygenic photosynthesis
- Prokaryotes: Both True Bacteria (Eubacteria) and Cyanobacteria (Blue-green algae) belong to Kingdom Monera and share prokaryotic traits (no nucleus, 70S ribosomes, peptidoglycan walls).
- Photosynthesis types:
- Most True Bacteria: If they photosynthesize, they are usually anoxygenic (do not produce oxygen, e.g., purple sulfur bacteria).
- Cyanobacteria: They have Chlorophyll a (similar to green plants) and perform oxygenic photosynthesis (splitting water to release O2).
- Unique Pigments: They also contain phycobiliproteins (phycoerythrin and phycocyanin).
