i don't know exactly what question you are trying to say but i will say that prokayotes are bacteria, and archea bacteria and they have no real organelles to name but they do have a cytoplasm and a band of RNA. they are used primarily in the lab to study evolution....i hope that helped

Protein Inclusion
When genes from one organism are expressed in another inclusion bodies are sometimes formed. This is especially true when large evolutionary distances are crossed: a cDNA isolated from Eukarya for example, and expressed as a recombinant gene in a prokaryote risks the formation of the inactive aggregates of protein known as inclusion bodies. While the cDNA may properly code for a translatable mRNA, the protein that results will emerge in a foreign microenvironment. This often has fatal effects, especially if the intent of cloning is to produce a biologically active protein. For example, eukaryotic systems for [[carbohydrate modification]] and membrane transport are not found in prokaryotes. The internal microenvironment of a prokaryotic cell (pH, osmolality) may differ from that of the original source of the gene. Mechanisms for folding a protein may also be absent, and hydrophobic residues that normally would remain buried may be exposed and available for interaction with similar exposed sites on other xenogenic proteins. Processing systems for the cleavage and removal of internal peptides would also be absent in bacteria. The initial attempts to clone insulin in a bacterium suffered all of these deficits, and human insulin was ultimately expressed in eukaryotic host cells which could supply the proper processing and modification enzymes to avoid the formation of insoluble precursor forms. In addition, the fine controls that may keep the concentration of a protein low will also be missing in a prokaryotic cell, and overexpression can result in filling a cell with xenogenic protein that, even if it were properly folded, would precipitate by saturating its environment.

That wikipedia page has more information if you need it, but hopefully that answers your question.

Inclusions within prokaryotes are usually remnants of pinocytotic and phagocytic vesicles,Phagocytosis is "cell eating" ie the process by which cells intake an extracellular food particle, and Pinocytosis is "cell drinking", same as Phagocytosis but in this case the food is in liquid form.

Extra storage of nutrients that they can access when needed.
