Presentation Transcript

  1. 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
