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.
Eukaryotes are organisms, including humans, whose cells have a well defined membrane-bound nucleus (containing chromosomal DNA) and organelles. The division between prokaryotes and eukaryotes reflects the existence of two very different levels of cellular organization.Distinctive types of prokaryotes include extremophiles and methanogens; these are common in some extreme environments.owever, two organelles found in many eukaryotic cells, mitochondria and chloroplasts, contain ribosomes similar in size and makeup to those found in prokaryotes. This is one of many pieces of evidence that mitochondria and chloroplasts are themselves descended from free-living bacteria.
