By now you are getting the idea that what seems like clear lines drawn between eukaryotic cells and prokaryotic cells may be not quite as clear as you previously thought. For example, let's think about cell walls. The prokaryotes and some eukaryotes have cell walls, but they aren't made of the same material. The cell membranes of archaebacteria and eubacteria are structured differently, but they both have cell membranes, as do eukaryotes. It's this variation on a theme that people interested in life science find fascinating. The fascination grows as scientists manipulate prokaryotes and eukaryotes through the cells' genes.
