- Prokaryotes: unicellular, microorganisms that lack organelles
- Archaea & bacteria
| Cell Type | Prokaryote | Eukaryotes |
| Size | Smaller | Bigger |
| Multi or Uni | Uni | Multi |
| Organelles | No (Nucleus) | Yes (Nucleus) |
| Cell Wall | Yes | Plants, Fungi, and some Protists |
| Cytoplasm | No cytoskeleton | Cytoplasm streaming |
| Ribosomes | Yes: smaller, diff proteins | Yes: bigger |
| DNA | Yes: singular, short, circular chromosome w/o histones
Usually no introns Less DNA that is in the nucleoid/cytoplasm Some contain plasmids |
Yes: multiple linear packaged with histone proteins & capped w/ telomeres
Usually has introns Chromosome enclosed in nucleus → large genome
|
| Cell Division | Binary Fission | Meiosis or Mitosis |
| Transfer of DNA | Only fragments | Thru meiosis |
| Flagella and Cilia | When present are made from globular protein flagellin & not microtubules enclosed by plasma membrane | When present are of protein tubulin “9 + 2” array |
