3. Know What do you know about archaebacteria? Evidence Page # “I don’t know anything.” is not an acceptable answer. Use complete sentences. 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.

4. Clarifying ?s Information Page # Archaebacteria bacteria- single-celled prokaryotes (no nucleus) having circular DNA shapes1. sphere2. rod3. spiral4. Curved rod5. Branched chain flagellum - Long whip-like structure movement1. flagellum2. wind3. water Examples: deep sea volcanic vents, geysers, hot springs Example: skin (swimming pool granuloma) archaebacteria - Live in extreme environments e.g. acidic, extreme heat, no oxygen eubacteria - Live everywhere else reproduction1. 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.

5. Clarifying ?s Information Page # Archaebacteria roles1. Fuel productionExample: methane 2. Food productionExample: yogurt and cheese 3. DecomposersExample: compost 4. diseasesExample: lymes disease, gangrene Example: strep throat, staph infection, food poisoning (salmonella and botulism) Infectious disease - Illness can be passed from one organism to another Example: Penicillin, Erythromyacin, Amoxicillin antibiotic - kills bacteria without harming other cells 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. survival Summary:
