| stimulus | change in an organisms surroundings that cause an organism to react |
| response | an action or change in behavior |
| development | process of change that occurs during an organisms lifetime |
| Redi (Francesco) | Italian doctor who helped disproved spontaneous generation |
| Pastuer (Louis) | French chemist who finally disproved spontaneous generation with broth experiments |
| needs of livings | food, water, living space, stable internal conditions |
| autotroph | can make their own food |
| heterotroph | cannot make their own food; must eat other organisms |
| homeostasis | maitaining stable internal conditions |
| classification | the process of grouping things based on their similarities |
| taxonomy | the science of classification |
| taxonomist | a scientist who specializes in classification |
| binomial nomenclature | Linnaeus's naming system; meaning 'two names' |

| prokaryotes | organisms whose cell do NOT have a nucleus |
| eukaryotes | organisms whose cells do have a nucleus |
| Archaea | domain (and kingdom) of "ancient" single celled organisms found in extreme environments |
| Eukarya | Domian of organisms whose cells have a nucleus in them; includes Kingsoms fungi, protist, animal and plant |
| Bacteria | domain (and kingdom) of prokaryote organisms that are singled celled and live almost everywhere; they can be helpful and harmful |
| Protists | kingdom of mostly unicellular organisms whose cells have a nuclues, but are not plants, animals or fungi; odds and ends kingdom |
| Fungi | Kingdom that is mostly multicellular, heterotrophs (consumers) that absorb their food; the Great Decomposers |
| Plants | Kingdom of multicellular autotrophs; cells have a nucleus |
| animals | kingdom of multicellular heterotrophs that can usually move; cells have a nucleus |
