Slide3Unique Traits
Archaebacteria
Found in extreme habitats with no oxygen
Cell walls made of proteinsEubacteriaFound everywhereCell walls made of amino acids and sugars
Slide4Major Phyla

Methanogens
-make methaneHalophiles-like high salt environmentsThermoacidophiles-like high heat and acidic conditionsEubacteria

Slide5Major Habitats
Archaebacteria
Meth-swamps, cow intestines, sewage treatment plants
Halo-lakes with high salt (Salt Lake, Utah and Dead Sea, Middle East)Thermo-hot springs, volcanic vents at bottom of the oceanEubacteria
Almost everywhere, including:
On and in other organisms
Ponds
Soil
Slide6Major Niches
Archaebacteria
Most are Chemosynthetic
autotrophsEubacteriaHeterotrophic- are parasites or decoposers
Autotrophic-Photosynthetic or Chemosynthetic

Slide9Reproduction in Bacteria
Binary Fission-makes an exact copy
of itself; done most often
Bacteria copies its chromosome.Chromosome and copy attach to cell membrane.Cell grows.
Partition forms between chromosomes and cells divide.
Can take as little as 20 minutes in some species.
Conjugation—sexual reproduction
Bacteria sends all or part of its chromosome across a bridge (
pilus
) to another bacteria.
Results in bacteria with a new genetic composition.
