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.
Cell walls can be composed of polysaccharides, proteins, lipids, or a combination of these. Cell walls provide increased mechanical strength and resistance to lysis by osmotic shock (water moving into the cell). Cell walls are found in the cells of eubacteria, archaebacteria, fungi, algae, and plants. Almost all eubacterial species have cell walls containing a polysaccharide called peptidoglycan. Among the eubacteria, differences in cell wall structure are a major feature used in classifying these organisms.
