All cells, whether they are prokaryotic or eukaryotic, have some common features. The common features of prokaryotic and eukaryotic cells are: 1  DNA, the genetic material contained in one or more chromosomes and located in a nonmembrane bound nucleoid region in prokaryotes and a membrane-bound nucleus in eukaryotes.he common features of prokaryotic and eukaryotic cells are: 1  DNA, the genetic material contained in one or more chromosomes and located in a nonmembrane bound nucleoid region in prokaryotes and a membrane-bound nucleus in eukaryotes.
Eukaryotic cells, while very similar in function to prokaryotic cells, are much larger and more complex. They are typically characterized by the presense of a prominent, more or less central nucleus. Viewed through a light microscope, this nucleus is by far the most striking visible feature of the cell. Plant cells have cell walls in addition to plasma membranes, not instead of plasma membranes. 2  Plant cell walls are composed all or partially of a carbohydrate called. , 3  which is quite different from the peptidoglycan of prokaryotic cell walls.
