• 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

(9)

• For energy, produce methane from carbon dioxide and

hydrogen gas

• Live in deep swamps

• Anaerobic

• Die in the presence of oxygen

(7)

• Methanogenic archaea are a big part of sewage

treatment.

(11)

• Live in extreme conditions

• 2 kinds

• Thermophiles – live in hot environments

• Halophiles – live in salty environments

• Same as regular bacteria: everywhere

Don’t easily Cultivate in lab

• Resistant enzymes in laundry soap.

(13)

• It helps with PCR

(14)

• They help in antibiotics

(12)

• No illnesses solely by archaea

• Form mutual and commensal

relationships

(7) Reticulitermes

flavipes

Prokaryotic Eukaryotic

No nucleus or Internal Compartments Have internal compartments

Always unicellular Mainly multicellular

Reproduce through Binary Fission Reproduce sexually, or by mitosis

Anaerobic and aerobic Mainly aerobic

Simple locomotion Complicated locomotion
