Classification Flashcards
Arrangement of animals and plants in taxonomic groups according to their similarities (kingdom and phylum in animals, division in plants, and class, order, family, genus, and species).
Classification
Naming, describing and classifying organisms and includes all plants, animals and microorganisms of the world.
Taxonomy
A system for naming plants and animals by means of two Latin names. The first indicating the genus and the second the species to which the organism belongs.
Binomial nomenclature
Group of one or more populations of an organism or organisms seen by taxonomists to form a unit.
Taxon
Ranking used in biological classification that is below a family and above a species level, group of species that are structurally similar or phylogenetically related.
Genus
Taxonomic rank in classification of organisms between genus and order.
Family
Taxonomic rank in classifying organisms, below the class, and made up of families sharing a set of similar nature or character.
Order
Taxonomic rank below the phylum (or division) and above the order.
Class
Taxonomic rank at the level below Kingdom and above Class in biological classification, especially of animals.
Phylum
Second highest taxonomic classification for the kingdoms plants and fungi, between kingdom level and class level.
Division
Taxonomic rank that is composed of smaller groups called phyla (or divisions, in plants).
Kingdom
Highest taxonomic rank of organisms in which there are three groupings: Archaea, Bacteria and Eukarya.
Domain
Evolutionary development or history of a species or of a taxonomic group of organisms.
Phylogeny
The sum of the relatively fixed personality traits and habitual modes of response of an individual.
Characters
Average rate at which a species’ genome accumulates mutations, used to measure their evolutionary divergence and in other calculations.
