Inclusion bodies of blue-green, purple and green photosynthetic bacteria are

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 also inclusion bodies found in blue green and purple and green photosynthetic bacteria.
