2. Know What do you know about archaebacteria? “I don’t know anything.” is not an acceptable answer. Use complete sentences. Evidence After listening to the PowerPoint lecture, come back here and list evidence to explain why your answer to the above question is or is not a good answer. You may also use other outside sources to help you respond. Page #

3. Archaebacteria Information Clarifying ?s bacteria - single-celled prokaryotes (no nucleus) having circular DNA shapes 1. sphere 2. rod 3. spiral 4. Curved rod 5. Branched chain movement 1. flagellum 2. wind 3. water flagellum - Long whip-like structure archaebacteria - Live in extreme environments e.g. acidic, extreme heat, no oxygen Examples: deep sea volcanic vents, geysers, hot springs eubacteria - Live everywhere else Example: skin (swimming pool granuloma) reproduction 1. Asexual – cloning – binary fission (cell divides into two identical cells.) 2. Sexual – Two parents combine DNA to form a new cell. conjugation - DNA is transferred from one organism to another through thread-like structures. Page #

4. Archaebacteria Information Clarifying ?s survival 1. autotrophic - Make own food using sun or chemicals 2. heterotrophic - Eats other things 3. endospore - A thick-walled structure forms inside the bacteria that holds and protects the DNA during unfavorable environmental conditions. roles 1. Fuel production Example: methane 2. Food production Example: yogurt and cheese 3. Decomposers Example: compost 4. diseases Example: lymes disease, gangrene Infectious disease - Illness can be passed from one organism to another Example: strep throat, staph infection, food poisoning (salmonella and botulism) antibiotic - kills bacteria without harming other cells Example: Penicillin, Erythromyacin, Amoxicillin Summary: Page #
