Question

do prokaryotes have a cell membrane?

Answer 1

Yes, prokaryotes do have a cell membrane. In fact, all prokaryotic cells possess a cell membrane, which is a vital component that encloses the cell's contents and regulates the movement of substances in and out of the cell. The cell membrane is typically composed of a phospholipid bilayer with embedded proteins, similar to eukaryotic cells, but lacks certain structures such as sterols in most bacteria. Prokaryotes include bacteria and archaea, both of which have this essential feature.
