Know: What roles does bacteria play
in human lives?
Archaebacteria vs Eubacteria
Archaebacteria
Characteristics:
Unicellular, prokaryotes,
autotrophs and
heterotrophs
Most can’t move
Resemble early life forms
Eubacteria
• Characteristics:
• Unicellular,
prokaryotes,
autotrophs and
heterotrophs
• Most are beneficial
• Some harmful--Strept
throat, food poison
Archaebacteria vs Eubacteria
Archaebacteria
• Habitat:
• Extreme environments:
Acidic,no oxygen, Hot
Springs
Eubacteria
• Habitat:
• Everywhere EXCEPT
extreme areas– skin
bacteria
Archaebacteria vs Eubacteria
Archaebacteria
Eubacteria
• Food:
• Some capture sunlight
(photosynthesis), others
decaying material Ex. Meat
or milk
• Food:
• Same as archaebacteria,
some use hydrogen or
methane (chemosynthesis)
Ex. Coal mine methane gas

• Impact:
• Nature’s recyclers– returns
basic chemicals to the
environment

Some live inside humans
Used to clean up oil spills
Existed on earth for billions
of years
Archaebacteria vs Eubacteria
• Common Features:
• Both come in various shapes and sizes:
1. Rods
2. Spirals
3. Spherical
Archaebacteria vs Eubacteria
• Common Features:
• Some have flagellum (whip) for movement
Archaebacteria vs Eubacteria
• Common Features:
Reproduction:
1. Asexual: divides into 2 identical cells
2. Sexual: 2 parents combine DNA to form new
cell
3. Conjugation: Transfer DNA through
thread-like structure
