Archaebacteria

bacteria - single-celled prokaryotes (no nucleus) having circular DNA

shapes 1. sphere 2. rod 3. spiral 4. Curved rod 5. Branched chain

flagellum - Long whip-like structure

movement 1. flagellum 2. wind 3. 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

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.

Archaebacteria

roles 1. Fuel production Example: methane2. Food production Example: yogurt and cheese3. Decomposers Example: compost4. diseases Example: 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.
