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.
Like the eukaryotic cell, they have a cell membrane (plasma membrane) and cytoplasm with ribosomes (protein manufacturing sites) and enzymes to carry out all the metabolic reactions. Prokaryotes also usually have a special type of cell wall exterior to the cell membrane.
