Classification Flashcards
Classification
the arrangement of animals and plants in taxonomic groups according to their observed similarities
Taxonomy
the branch of science concerned with classification, especially of organisms; systematics.
Binomial nomenclature
a system of nomenclature in which each species of animal or plant receives a name of two terms of which the first identifies the genus to which it belongs and the second the species itself.
Taxon
a taxonomic group of any rank, such as a species, family, or class.
Genus
a class of things that have common characteristics and that can be divided into subordinate kinds.
Family
A taxonomic rank in the classification of organisms between genus and order. (2) A taxonomic group of one or more genera, especially sharing a common attribute.
Order
a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes
Class
is a taxonomic rank, as well as a taxonomic unit, a taxon, in that rank.
Phylum
a principal taxonomic category that ranks above class and below kingdom.
Division
a rank that if treated as a division of a genus or subgenus is deemed to be of subgeneric rank for the purposes of nomenclature. 3. A taxon at the rank of division
Kingdom
The highest classification into which living organisms are grouped in Linnean taxonomy, ranking above a phylum.
Domain
In biological taxonomy, a domain (Latin: regio), also superkingdom or empire, is the highest taxonomic rank of organisms in the three-domain system of taxonomy designed by Carl Woese, an American microbiologist and biophysicist.
Phylogeny
the branch of biology that deals with phylogenesis.
Characters
A character is any letter, number, space, punctuation mark, or symbol that can be typed on a computer. The word “computer,” for example, consists of eight characters
Molecular clock
The molecular clock is figurative term for a technique that uses the mutation rate of biomolecules to deduce the time in prehistory when two or more life forms diverged.
