BACTERIA 2 PROKARYOTIC CELLS

1
BACTERIA 2 PROKARYOTIC CELLS

• Break down / Decompose
• Waste sewage, oil spills
• Dead stuff
• Food in digestive system
• Nitrogen Fixation change nitrogen in the air to
  a form plants can use

5. HELPFUL BACTERIA

• Cause Disease
• Invade and multiply inside the body
• Some release poisons
• Cause food to spoil

6. HARMFUL BACTERIA

• Antibiotics medicine that attacks kills only
  bacteria cells and not body cells
• Vaccines weak form of bacteria/toxin injected
  into body to cause antibodies to be made

7. FIGHTING BAC
- Strep Throat- E. coli- Salmonella- MRSA-
Pneumonia- Urinary Tract Infection
- Botulism- Tetanus - Necrotizing Fasciitis-
Meningitis
8.BACTERIAL DISEASES

BACTERIA 2 PROKARYOTIC CELLS
antibiotics

• Bacteria not killed by antibiotics because of
  special genes
• SUPERBUGS
• Happens when antibiotics are used too much or
  when they are not needed
• ex MRSA

9.ANTIBIOTIC RESISTANCE

ARCHAEA PROKARYOTES IN EXTREME ENVIRONMENTS

• Unicellular, Prokaryotic
• Live in extreme environments
• Similar to bacteria in some ways
• Do not cause disease

1.ARCHAEA CHARACTERISTICS

• Methanogens - produce natural gas (methane) in
  cows stomachs
• Halophiles - live in really salty lakes and ponds
• Thermophiles - live in extreme heat (geysers /
  deep sea vents) or cold (glaciers)
