Lesson 2

• Eubacteria and Archaebacteria are the two prokaryotic kingdom
• Archaebacteria are autotrophic organisms
• Photosynthetic Archaeans were referred to as the Blue-Green Algae
• Nostoc, Anabaena, Oscillatoria are Examples of Archaebacteria
• Chemosynthetic organisms are found of swamps, in the soil, and underwater volcanic vents
• The 3 Chemical Substances are Ammonia, Methane, And Hydrogen Sulfide
• The 3 types of Extreme Archaeans are Halophiles, Acidophiles, and Thermophiles
• Halophile is an extreme archaean that lives in salt water
• Acidophile is an extreme archaean that thrives on acidic environments
• Thermophile is an extreme archaean that survives high temperatures
• Autotrophs could make their own food
• Heterotrophs cannot make its own food
• Saprotrophs could gain nutrients from decaying organic matter
• Peptidoglycan is the main component of bacteria cell wall
• Cell walls are composed of Cellulose
• Binary Fission is the simple division of one cell into two cells
• Conjugation simple sexual methods in bacteria
• Endospores are structures that are formed when environmental conditions become adverse
