Archaebacteria & Eubacteria EQ: What are the similarities and differences between the Archaebacteria and Eubacteria Kingdoms? Archaebacteria & Eubacteria EQ: 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 & Eubacteria EQ: 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 Habitat Eubacteria: everywhere Differences Archae: no peptidoglycan Cell Walls DNA Eubacteria: has peptidoglycan Archaebacteria is more like the genetic sequence of eukaryotes Archaebacteria & Eubacteria EQ: 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 Archaebacteria & Eubacteria EQ: What are the similarities and differences of the Archaebacteria and Eubacteria Kingdoms? 3 Ways Eubacteria Obtain Nutrients From other organisms: parasites/saprophytes Gets nutrients from dead or decaying organisms Photosynthesis Chemosynthesis Archaebacteria & Eubacteria EQ: What are the similarities and differences of the Archaebacteria and Eubacteria Kingdoms? • Gram Staining • Helps identify the type of bacteria by the presence of peptidoglycan in the cell walls Archaebacteria & Eubacteria EQ: What are the similarities and differences of the Archaebacteria and Eubacteria Kingdoms? Gram Staining Results Negative Results Positive Results Pink Purple No Peptidoglycan Peptidoglycan Archaebacteria Eubacteria Archaebacteria & Eubacteria EQ: What are the similarities and differences of the Archaebacteria and Eubacteria Kingdoms?

Archaebacteria & Eubacteria EQ: What are the similarities and differences of the Archaebacteria and Eubacteria Kingdoms? 3 Basic Shapes Cocci (sphere) Bacilli (rod) Spirilla (spiral) Archaebacteria & Eubacteria EQ: What are the similarities and differences of the Archaebacteria and Eubacteria Kingdoms? Archaebacteria & Eubacteria EQ: What are the similarities and differences of the Archaebacteria and Eubacteria Kingdoms? 3 Growth Patterns Diplo (paired) Staphylo (grapes) Strepto (chain) Live Bacteria Videos Rowland Institute At Harvard • Swarming E. Coli • Swimming Synechococcus • Swimming Rhodobacter Archaebacteria & Eubacteria EQ: What are the similarities and differences of the Archaebacteria and Eubacteria Kingdoms? Grows RAPIDLY !!!!!!!!!!!!! Highest reproductive potential !! Diplococcus Streptococcus Staphyococus Archaebacteria & Eubacteria EQ: What are the similarities and differences of the Archaebacteria and Eubacteria Kingdoms? Reproduction Asexual Reproduction: Binary Fission Sexual Reproductive: Conjugation ….chromosomes are transferred through the pilus Conjugation Animation 2 1 3 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.
