- The other two are the bacterial and archaeal domains.
- Organisms called eukaryotes have nuclei and membrane-bound organelles in their cells.
- Eukaryotic creatures come in a great variety, including most algae, all animals, plants, fungus, and protists.
- Eukaryotes are multicellular or unicellular organisms.
