Domain Bacteria
Domain Bacteria only contains 1 Kingdom: Eubacteria.
Eubacteria (true bacteria) are prokaryotes whose cell walls contain peptidoglycan. They can be beneficial or cause disease.
Eubacteria are a diverse group that can survive in many different environments.

Domain Archaea
Domain Arachaea only contains 1 kingdom: Archaebacteria.
Archaeabacteria are thought to be more ancient than eubacteria.
Archaea are diverse in shape and nutrition requirements.
They are called extremophiles because they can live in extreme environments (ex: salty or extremely hot – deep oceans, hot springs, & swamps.
NO PEPTIDOGLYCAN
