Domains and Kingdoms

Domain Bacteria

• Eubacteria – prokaryotic and cell walls contain peptidoglycan.

• Some are aerobic and some are anaerobic.

• Most are heterotrophic and some are autotrophic

• More abundant than any other organism

BACTERIAL COLONY THAT IS ANTIBIOTIC BACTERIAL COLONY THAT IS ANTIBIOTIC RESISTANTRESISTANT

Domain Archaea

• More closely related to eukaryotes

• Cell walls do not contain peptidoglycan

• Can be autotrophic or heterotrophic

• Live in extreme environments – hot springs, thermal vents, salty lakes.
