1. Diversity of Living Things
Archaea and Bacteria

2. Prokaryotes Lack a nucleus Lack organelles Types of Bacteria
Pro = before, karyon = nucleus
Lack organelles
No mitochondria, chloroplasts
Types of Bacteria

3. Eukaryotes
Have a contained nucleus & Organelles

4. Kingdom ARCHAEA Oldest Cell walls Anaerobic lack peptidoglycan
Extreme conditions
Anaerobic

5. Archaea Characteristics
3 Groups of Archaea
Thermoacidophile
Heat-Acid Bacteria
Methanogens
Methane Bacteria
Halophiles
Salt Bacteria

6. BACTERIA (EUBACTERIA)
More evolved
Have Peptidoglycan
Humans have 10 x more bacterial cells than our own

7. GOOD BACTERIA: SAPROPHYTES BIOREMEDIATION PROBIOTICS
Release digestive enzymes and break material down
BIOREMEDIATION
Uses bacteria to destroy, transform or immobilize environmental contaminants
PROBIOTICS
Help maintain health and prevent disease

8. Other Good Bacteria in Your Body
Vitamin K, B
Balance
Lactase
absorption of Mg

9. Harmful Bacteria Syphilis Lyme Disease Anthrax
Many can be killed using sanitizer and antibacterial wipes
Syphilis
Lyme Disease
Carried by ticks
Fever, headache, fatigue, depression, and a characteristic circular skin rash
Treated with antibiotics
An STI
Often confused with other diseases
If untreated, can damage the heart, aorta, brain, eyes, and bones.
Can be fatal
Treated with antibiotics
Anthrax
Used as a biological weapon
Almost all forms are lethal
Presents as cold/flu-like symptoms
Eating an infected piece of meat can cause gastrointestinal difficulty, vomiting of blood, severe diarrhea, acute inflammation of the intestinal tract, and loss of appetite

10. Classification of Bacteria

12. Classification of Bacteria
Source of food
Heterotroph
Takes up organic molecules from environment or by eating other organisms
Photoautotroph
Uses sunlight (Photosynthesis)
Photoheterotroph
Uses light energy and energy from other organisms
Chemoheterotroph
Uses energy released through chemical reactions
