Taxonomy Lab (student handout)
Introduction (continued):
The three domains are Eubacteria, Archaea, and Eukarya. The domain classifications are based on the type of cells that
make up the organism. Prokaryotic cells are those that have no nucleus or membrane-bound organelles. Eukaryotic cells,
on the other hand, do have a nucleus and membrane-bound organelles.
• Kingdoms are divided into smaller groups called phyla (singular, phylum). A phylum is divided into classes; classes into orders;
orders into families; families into genera (singular, genus); and a genus is divided into species. Therefore, all organisms can be
described in terms of their hierarchical taxonomic classification scheme:
