1. Classification and Structure
Bacteria:
Classification and Structure

2. What are the 6 Kingdoms? Archaebacteria Eubacteria Protists Fungi
Plants
Animals

3. We are looking at the first two
Archaebacteria
Eubacteria

4. Classification of Bacteria
Archaebacteria: extremists
Eubacteria:
Heterotrophs
Photosynthetic autotrophs
Chemosynthetic autotrophs

5. Archaebacteria Live in extreme locations: Oxygen-free environments
Concentrated salt-water
Hot, acidic water

6. Eubacteria - Heterotrophs
Found everywhere
Parasites: live off of other organisms
Saprobes: live off of dead organisms or waste (recyclers)

7. Eubacteria: Photosynthetic Autotrophs
Photosynthetic: make their own food from light
Cyanobacteria: blue-green, yellow, or red
ponds, streams, moist areas

8. Eubacteria: Chemosynthetic Autotrophs
Get energy by breaking down inorganic substances like sulfur and nitrogen
Make nitrogen in the air usable for plants {Very Important}

9. Structure of Bacteria Two parts to Bacteria Structure: Arrangement
Shape

10. Arrangement Paired: diplo Grape-like clusters: staphylo
Chains: strepto

11. Shape
Rod: bacillus
Spheres: coccus
Spirals: spirillum

12. Examples Streptococcus: chains of spheres
Staphylospirillum: Grapelike clusters of spirals
Streptobacillus: Chains of rods
