Bacteria:

Classification and Structure

what are the 6 kingdoms
What are the 6 Kingdoms?
  • Archaebacteria
  • Eubacteria
  • Protists
  • Fungi
  • Plants
  • Animals
we are looking at the first two
We are looking at the first two
  • Archaebacteria
  • Eubacteria
classification of bacteria
Classification of Bacteria
  • Archaebacteria: extremists
  • Eubacteria:
    • Heterotrophs
    • Photosynthetic autotrophs
    • Chemosynthetic autotrophs
archaebacteria
Archaebacteria
  • Live in extreme locations:
    • Oxygen-free environments
    • Concentrated salt-water
    • Hot, acidic water
eubacteria heterotrophs
Eubacteria - Heterotrophs
  • Found everywhere
  • Parasites: live off of other organisms
  • Saprobes: live off of dead organisms or waste (recyclers)
eubacteria photosynthetic autotrophs
Eubacteria: Photosynthetic Autotrophs
  • Photosynthetic: make their own food from light
  • Cyanobacteria: blue-green, yellow, or red
  • ponds, streams, moist areas
eubacteria chemosynthetic autotrophs
Eubacteria: Chemosynthetic Autotrophs
  • Get energy by breaking down inorganic substances like sulfur and nitrogen
  • Make nitrogen in the air usable for plants {Very Important}
structure of bacteria
Structure of Bacteria
  • Two parts to Bacteria Structure:
    • Arrangement
    • Shape
arrangement
Arrangement
  • Paired: diplo
  • Grape-like clusters: staphylo
  • Chains: strepto
shape
Shape
  • Rod: bacillus
  • Spheres: coccus
  • Spirals: spirillum
examples
Examples
  • Streptococcus: chains of spheres
  • Staphylospirillum: Grapelike clusters of spirals
  • Streptobacillus: Chains of rods
