|---|
| prokaryote | any bacterial cell |
| membrane bound organelles | not present in archae or eubacteria |
| eubacteria | minus introns, plus peptidoglycan cell walls |
| archaebacteria | plus introns, minus peptidoglycan cell walls |
| extremophiles | archaebacteria that live in hot (thermophiles), salty (halophiles), or acidic (acidophiles) places |
| gram negative | eubacteria with lipopolysaccharides covering the outersurface of a thin peptidoglycan cell wall |
| cocci | spherical bacteria |
| bacilli | rod shaped bacteria |
| endotoxins | cell walls of Staphlococcus aureus (causes toxic shock syndrome) contain one example of these |
| lactobacilli | used in making dairy products; cause milk to sour & turn fruit juices to vinigar instead of wine |
| E coli | used to clone genes & help digest food |
| helicobacteria | normal stomach populations that can cause ulcers if their numbers become abnormally high or if the mucous coating the stomach walls is too thin |
| lyme disease | transmitted by bacteria in tick saliva |
| cholera | caused by vibrio bacteria in fecal contaminated water |
| anthrax | spores in soil where infected animals were buried cause lung failure if inhaled |
| chemoautoroph | one of the strategies used by bacteria, the most metabolically diverse kingdom; use inorganic compounds and hot vent heat as source of energy to synthesize organic compounds |
