Differentiate between Cell organelles and Cell inclusions
Cell organelle is a specific part of a cell that has a specific function to do whereas inclusions are basically reserve materials in prokaryotes.They lie within the cytoplasm .They are granules such as the phosphate granule and cyanophycean granule.
Cytoplasm is a cell organelle within which these granules called inclusions lie.
Plasma membrane is not a organelle .It is just a membranous structure which forms a cover on various cell organelles .
