 Non-living: Need a host to reproduce  Lysogenic Cycle: break out of the cell when reproduction is finished.  Lytic Cycle: Can remain dormant for long.

Classification and Structure Bacteria: Classification and Structure

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

We are looking at the first two Archaebacteria Eubacteria

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

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

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

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

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 Two parts to Bacteria Structure: Arrangement Shape

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

Shape Rod: bacillus Spheres: coccus Spirals: spirillum

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