Answer
Inclusion bodies are:
- Non-membrane-bound granular structures
- Store reserve materials in prokaryotic cytoplasm
- Types:
- Phosphate granules (polyphosphate/volutin granules)
- Glycogen granules (energy storage)
- Cyanophycean granules (cyanophycin) – nitrogen reserve in cyanobacteria
- Gas vacuoles – buoyancy regulation
- Sulfur granules – in sulfur bacteria
These structures accumulate when specific nutrients are abundant and serve as metabolic reserves during nutrient scarcity.
