3
Archaea and Bacteria the two prokaryotic
kingdoms
4
Archaea

• Have elements common to both Prokaryotes and
  Eukaryotes
• Membrane structure
• Ribosomes
• But NO NUCLEUS
• Live as unicellular organisms, but sometimes in
  groups. Each cell is fully capable of all of
  lifes requirements.

5
Archaea are Extremophiles live well in heat,
salt, low oxygen
6
Archaea

• Food types include phototrophs, chemotrophs and
  heterotrophs
• Ecological roles Are producers, consumers and
  decomposers
• Digestion external to their bodies
• Example haloarchabacteria
• Human uses of those that produce methane are
  used to make natural gas for farms
• Found in Salt beds, Yellowstone geysers, and
  local mud of local ponds.

7
Bacteria Also Prokaryotes

• Found in almost every type of environment,
  including anaerobic (no oxygen)
• Prokaryotic

8
Bacterial Shapes
Round coccus
Rod bacillus
Rod bacillus
Spiral spirillum
9
Bacteria

• Body forms may be unicellular or in groups or
  clumps. Rod shaped ones sometimes line up to
  form hair-like filaments.
• Each cell is fully capable of all of lifes
  processes

10
Bacterial Reproduction FISSION which is Asexual
11

• Major Roles in Environment Producers,
  decomposers
• Human uses of genetic engineering, fermentation
  of cheeses, beverages soysauce, bioremediation,
  yogurt making
• Diseases Strept throat, TB, Staph, pimples,
  bacterial meningitis, pneumonia, Salmonella food
  poisoning
• Examples Staphylococcus, Streptococcus, E.
  coli, Tuberculosis, Bacillus thuringiensis,
  Pneumococcus.

12
Bacteria

• Food Preservation techniques are to prevent
  bacteria from growing
• Bacteria need
• Moisture
• Proper temperature
• Proper pH
• Proper salinity
