Introduction to Monera: Kingdom Archaebacteria and Kingdom Eubacteria Bio 11 Introduction to Monera: Kingdom Archaebacteria and Kingdom Eubacteria

The 6 Kingdoms

Is All Bacteria bad? Positive Negative Good for human digestion and nutrients synthesis Food production (dairy products) Source of antibiotics Production of vinegar from alcohol Diseases (tetanus, strep throat, etc.) Food spoilage Food poisoning Pollution of water (algal blooms) Skin infections

Experiment Time

Monera There used to be only 5 kingdoms, now we know there are 6 The kingdom Monera was split into two kingdoms: Eubacteria and Archaebacteria This was done because there are a few differences

Kingdom Archaebacteria Prokaryotic Unicellular No nucleus Heterotrophic Have a cell wall (chemically distinct, not set) Locomotion? What do you think? Archaebacteria are extremophiles, they can tolerate extreme conditions

Kingdom Eubacteria Prokaryotic Unicellular No nucleus Autotrophic OR heterotrophic Cell wall made of peptidoglycan Locomotion? Eubacteria is all other types of bacteria and cyanobacteria (often called blue-green algae)

What is the difference? Are both heterotrophs? What about cell wall components? Main thing is, they are both prokaryotes and that is what originally had them in the same Kingdom (Monera).
