The cells of all prokaryotes and eukaryotes hold two basic characteristics: a plasma membrane also described as a cell membrane, and cytoplasm.
The cells of prokaryotes are simpler than cells of eukaryotes. For instance, prokaryotic cells do not have a nucleus, while eukaryotic cells have a nucleus.
The component of the cell associated to as cytoplasm is somewhat complex in eukaryotes and prokaryotes. In eukaryotic cells, which possess a nucleus, the cytoplasm is within the plasma layer and the nuclear cover. In prokaryotes, which lack a nucleus, cytoplasm solely means everything found inside the cell membrane.
