what is the division of organisms into groups,or classes, based on characteristics
classification
the science of describing , naming, and classifing organisms
taxonomy
the largest most general groups
kingdom
their sorted into further classes
phylum
each class includes continuations one or more orders
class
the 4 th highest taxonomic category below class
order
the 5 th highest taxonomic category
family
a group of similar organsms
genus
smallest, most precise classification category
species
a kingdom made up of complex multicellular organisms that lack cell walls
Animalia
Chordates are animals possessing a notochord, a hollow dorsal nerve cord, pharyngeal slits, an endostyle, and a post-anal tail for at least some period of their life cycles.
chordata
Mammals are any members of a clade of endothermic amniotes distinguished from reptiles and birds by the possession of hair, three middle ear bones, mammary glands, and a neocortex
mammalia
A primate is a mammal of the order Primates. In taxonomy, primates include two distinct lineages, strepsirrhines and haplorhines
primate
The Hominidae, also known as great apes or hominids, are a taxonomic family of primates that includes seven extant species in four genera: Pongo, the Bornean and Sumatran orangutan; Gorilla, the eastern
hominide
A dichotomous key is a tool that allows the user to determine the identity of items in the natural world, such as trees, wildflowers, mammals, reptiles, rocks, and fish. Keys consist of a series of choices that lead the user to the correct name of a given item. “Dichotomous” means “divided into two parts”
dichotomous key
a specified sphere of activity or knowledge
domain
The Archaea constitute a domain or kingdom of single-celled microorganisms. These microbes are prokaryotes, meaning that they have no cell nucleus or any other membrane-bound organelles in their cells
Archaebacteria
Bacteria constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria have a number of shapes, ranging from spheres to rods and spirals
bacteria
In some biological taxonomy schemes, protists were a large group of diverse eukaryotic, mainly unicellular microorganisms, that do not form tissues. Formerly, these were assigned to the now-obsolete kingdom Protista
protista
A fungus is any member of the group of eukaryotic organisms that includes unicellular microorganisms such as yeasts and molds, as well as multicellular fungi that produce familiar fruiting forms known as mushrooms.
fungi
Plants, also called green plants, are multicellular eukaryotes of the kingdom Plantae. They form an unranked clade Viridiplantae that includes the flowering plants, conifers and other gymnosperms, ferns
plantae
