Archaebacteria & EubacteriaEQ: What are the similarities and differences between the
Archaebacteria and Eubacteria Kingdoms?
Characteristics of Bacteria• Domains: Archae &
Bacteria• Kingdoms: Archaebacteria
& Eubacteria• Prokaryotic Cells: cells
without a defined nucleus and cell organelles
• Unicellular Organisms• Microorganisms Cyanobacteria

Archaebacteria & EubacteriaEQ: What are the similarities and differences between the
Archaebacteria and Eubacteria Kingdoms?
• Monera formerly housed all bacteria, but now bacteria are divided into two kingdoms: Archaebacteria and Eubacteria
Archae: harsh, hostile environment
Eubacteria: everywhere
Archae: no peptidoglycan
Eubacteria: has peptidoglycan
Archaebacteria is more like the genetic
sequence of eukaryotes
Habitat
Cell Walls
DNA
Differences

Archaebacteria & EubacteriaEQ: What are the similarities and differences between the
Archaebacteria and Eubacteria Kingdoms?
• 3 Hostile Environments of Archaebacteria
• 1) Oxygen Free: Marshes, Digestive Tracts, Sewage
• 2) High Salt Content: Dead Sea, Great Salt Lakes
• 3) Hot Acidic Waters: Sulfur Springs, Ocean Vents

3 Ways Eubacteria Obtain NutrientsFrom other organisms: parasites/saprophytes
Gets nutrients from dead or decaying organisms
Photosynthesis
Chemosynthesis

• Gram Staining
• Helps identify the type of bacteria by the presence of peptidoglycan in the cell walls

Reproduction
Asexual Reproduction: Binary Fission
Sexual Reproductive: Conjugation ….chromosomes
are transferred through the pilus
Conjugation Animation

Bacteria “Mix-Up”Group 1
Map out a possible sequence of events predicting the spread of pneumococcus, a bacterium that causes pneumonia, in a crowded nursing home. Most of the residents in the nursing home are elderly and their immune systems are impaired. Consider all the people that pass by each day and who these people interact with outside their homes.
Group 2
Create a 3D model of the three shapes of bacteria AND the three bacterial growth patterns.
Group 3
Calculate the rate a bacterium cell replicates AND create a poster informing the public how to avoid and prevent the spread of bacterial infections.
