BIOL 1002 : BIO EXAM 1 NOTES
Document Summary
Taxonomic ranks = domain -> kingdom -> phylum -> class -> order -> family -> genus -> species liquid environment; use of flagella allows prokaryotes to disperse into new habitat, migrate toward nutrients, and leave unfavorable environments. Three domains of life = eukarya, bacteria, archaea. Bacteria and archaea consist entirely of prokaryotes helps strengthen the cell wall; unique to bacteria; the cell walls of archaea do not contain it. Bacteria and archaea range in size from 0. 2 to 10 micrometers in diameter. Eukaryotic cells range in size from 10 to 100 micrometers in diameter. Common shapes of prokaryotic cells = spherical, rodlike, and corkscrew-shaped. Carolus linnaeus swedish naturalist who establish modern taxonomy. Taxonomy the branch of biology that is concerned with naming and classifying. Genus group that includes a number of very closely related species. Species includes populations of organisms that can potentially interbreed under. Clades groups that include species linked by descent from a common ancestor.
