MicroBio: Artist Renderings - prokaryotes vs. eukaryotes

prokaryotic cells
A distinction between prokaryotes and eukaryotes (meaning true kernel, also spelled "eucaryotes") is that eukaryotes do have "true" nuclei containing their DNA, whereas the genetic material in prokaryotes is not membrane-bound. Eukaryotic organisms may be unicellular, as in amoebae, or multicellular, as in plants and humans. The difference between the structure of prokaryotes and eukaryotes is so great that it is considered to be the most important distinction among groups of organisms.

eukaryotic cells
The defining membrane-bound structure that differentiates eukaryotic cells from prokaryotic cells is the nucleus
