taxonomy the branch of biology that identifies, names, and classifies species based on natural features
binomial nomenclature the system of giving a two-word Latin name to each species; the first part is the genus and the second part is the species
genus (genera) taxonomic group of a closely related species
classification the group of organisms based on a set of criteria that helps to organize and indicate evolutionary relationships
hierarchical classification the method of classifying organisms in which species are arranged in categories from most general to most specific
rank a level in a classification scheme, such as phylum or order
taxon (taxa) a named group of organisms such as phylum Chordata or order Rodentia
ancestor an organism (or organisms) from which other groups of organisms are descended
anatomy the branch of biology that deals with structure and form, including internal systems
physiology the branch of biology dealing with the physical and chemical functions of organisms, including internal processes
phylogenetic tree a branch diagram used to show the evolutionary relationships among species
structural diversity a type of biological diversity that is exhibited in the variety of structural forms in living things, from internal cell structure to body morphology
prokaryotic a smaller, simple type of cell that does not have a membrane-bound nucleus
eukaryotic a larger, complex type of cell that does have a membrane-bound nucleus
dichotomous key an identification tool consisting of a series of two-part choices that lead the user to a correct identification
autotroph an organism that captures energy from sunlight (or sometimes non-living substances) to produce its own energy-yielding food
heterotroph an organism that cannot make its own food and gets its nutrients and energy from consuming other organisms
species diversity the variety and abundance of species in a given area
genetic diversity the variety of heritable characteristics (genes) in a population of interbreeding individuals
ecosystem diversity the variety of ecosystems in the biosphere
gene pool all the genes of all the individuals in a population
