• Archaea are prokaryotes
• They are unicellular
• They are the only kingdom in the domain of Archaea
• They are very diverse
• Similar to Eukaryotes

• Used to be two types of classifications, Prokaryotes and
Eukaryotes
• Archaea were, judging on the DNA sequence, found to
be much different than other prokaryotes, such as
Bacteria
• Carl Woese and George E. Fox came up with 3 different
domains: Bacteria, Archaea, and Eukarya
• There are two main phyla (though many smaller ones) in
the kingdom Archaea, which are in the domain Archaea:
Crenarchaeota and Euryarchaeota
• There are 3 main types of Archaea: methanogens,
extremophiles, and non-extreme archaea

• Archaebacteria is an incorrect term, as it was used
before Woese’s reclassification
• Archaea is the correct terminology

• Variety of shapes (spherical, rod, spiral)
• No membrane bound organelles
• The Archaea have no nuclei, mitochondria, endoplasmic
reticula, and a others
• Thick cytoplasm, though, which contains e’erthing
• Rigid cell wall with no peptidoglycan
• DNA is a singular circular molecule

• For energy, produce methane from carbon dioxide and
hydrogen gas
• Live in deep swamps
• Anaerobic
• Die in the presence of oxygen

• Methanogenic archaea are a big part of sewage
treatment.

• Live in extreme conditions
• 2 kinds
• Thermophiles – live in hot environments
• Halophiles – live in salty environments

• Same as regular bacteria: everywhere
