classification

a system used by scientists to group and sort living and non-living things based on the characteristics they share

taxonomy

the branch of science concerned with classification of organisms

Carolus Linnaeus

Father of Taxonomy; developed binomial nomenclature; his grouping system grouped organisms from kingdom through species

binomial nomenclature

developed by Carolus Linnaeus; names come from the organism’s genus and species

italicized, capitalized

In binomial nomenclature, the genus and species are \[capitalized/bolded/italicized/underlined\], and the genus is \[capitalized/bolded/italicized/underlined\].

dichotomous key

In each step of the _______________ _____, two choices are given with directions for what to do next. Each choice leads to either another choice or the identity of the object or organism.
