Bacteria l.jpg

Bacteria:

Classification and Structure


What are the 6 kingdoms l.jpg
What are the 6 Kingdoms?

  • Archaebacteria

  • Eubacteria

  • Protists

  • Fungi

  • Plants

  • Animals


We are looking at the first two l.jpg
We are looking at the first two

  • Archaebacteria

  • Eubacteria


Classification of bacteria l.jpg
Classification of Bacteria

  • Archaebacteria: extremists

  • Eubacteria:

    • Heterotrophs

    • Photosynthetic autotrophs

    • Chemosynthetic autotrophs


Archaebacteria l.jpg
Archaebacteria

  • Live in extreme locations:

    • Oxygen-free environments

    • Concentrated salt-water

    • Hot, acidic water


Eubacteria heterotrophs l.jpg
Eubacteria - Heterotrophs

  • Found everywhere

  • Parasites: live off of other organisms

  • Saprobes: live off of dead organisms or waste (recyclers)


Eubacteria photosynthetic autotrophs l.jpg
Eubacteria: Photosynthetic Autotrophs

  • Photosynthetic: make their own food from light

  • Cyanobacteria: blue-green, yellow, or red

  • ponds, streams, moist areas


Eubacteria chemosynthetic autotrophs l.jpg
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 l.jpg
Structure of Bacteria

  • Two parts to Bacteria Structure:

    • Arrangement

    • Shape


Arrangement l.jpg
Arrangement

  • Paired: diplo

  • Grape-like clusters: staphylo

  • Chains: strepto


Shape l.jpg
Shape

  • Rod: bacillus

  • Spheres: coccus

  • Spirals: spirillum


Examples l.jpg
Examples

  • Streptococcus: chains of spheres

  • Staphylospirillum: Grapelike clusters of spirals

  • Streptobacillus: Chains of rods
