Prokaryotic Inclusion Bodies & Reserves — NEET Biology
✅ Asked in NEET 2020Inclusion bodies: Reserve material in prokaryotic cells are stored in the cytoplasm in the form of inclusion bodies. These are not bound by any membrane system and lie free in the cytoplasm, e.g., phosphate granules, cyanophycean granules and glycogen granules. Gas vacuoles are found in blue green and purple and green photosynthetic bacteria.
Inclusion bodies are reserve materials (like phosphate, glycogen, cyanophycean granules) stored freely in prokaryotic cytoplasm without any membrane boundary. NTA tests this to check if students confuse inclusion bodies with membrane-bound organelles like vacuoles in eukaryotes. The critical mistake is thinking these reserves have a membrane—they don't. Remember: prokaryotes store nutrients as free cytoplasmic granules, while gas vacuoles (also membrane-free) help buoyancy in photosynthetic bacteria. This distinction between membrane-bound vs. non-membrane-bound storage is fundamental to prokaryotic cell structure and frequently appears in comparative cell biology questions.
