what are the parts of prokaryotic cells
All prokaryotic cells contain large quantities of genetic material in the form of DNA and RNA. Because prokaryotic cells, by definition, do not have a nucleus, the single large circular strand of DNA containing most of the genes needed for cell growth, survival, and reproduction is found in the cytoplasm.
Internal Structures of Prokaryotic Cells. 1  Plasma Membrane: The cell membrane is a double-layer of phospho lipids with associated proteins and other molecules. 2  It is essentially the âbagâ that holds all of the intracellular material and regulates the movement of materials into and out of the cell.
Prokaryotic ribosomes are smaller and have a slightly different shape and composition than those found in eukaryotic cells. Bacterial ribosomes, for instance, have about half of the amount of ribosomal RNA (rRNA) and one third fewer ribosomal proteins (53 vs. ~83) than eukaryotic ribosomes have.
