All life on Earth can be classified in one of three DOMAINS:
- BACTERIA: prokaryotic (no nucleus), single-celled organisms
- ARCHAEBACTERIA: most primitive bacteria
- EUKARYA: cells contain a nucleus which houses the DNA
Domain Eukarya is divided into multiple KINGDOMS:
- Plantae (plants)
- Fungi (fungi - mushrooms, yeast, mold)
- Animalia (animals)
- Protista (algae, protozoans)
- Monera (bacteria)
BINOMIAL NOMENCLATURE uses the GENUS and SPECIES to classify organisms.
