Actually, cell walls are found in both prokaryotes and eukaryotes. In plants (eukaryotic) the cell walls are composed of cellulose whereas in prokaryotes, the cell walls are composed of peptidoglycan.
Prokaryotes have only one lipid bilayer-the cell membrane (also known as the plasma membrane). Many prokaryotes also have a cell wall, but the cell wall is composed of proteins or long chain carbohydrates, not lipids.
