taxonomy
discipline of classifying organisms and assigning each organism a universally accepted name
binomial nomenclature
classification system in which each species is assigned a two-part scientific name
genus
group of closely related species, and the first part of the scientific name in binomial nomenclature
taxon
group or level of organization into which organisms are classified
family
group of genera that share many characteristics
order
group of similar families
class
group of similar orders
phylum
group of closely related classes
kingdom
large taxonomic group, consisting of closely related phyla
phylogeny
the study of evolutionary relationships among organisms
evolutionary classification
method of grouping organisms together according to their evolutionary history
cladogram
diagram that shows the evolutionary relationships among a group of organisms
eubacteria
kingdom of unicellular prokaryotes whose cell walls are made up of peptidoglycan
bacteria
domain of unicellular prokaryotes that have cell walls containing peptidoglycans
archaea
domain of unicellular prokaryotes that have cell walls that do not contain peptidoglycan
archaebacteria
kingdom of unicellular prokaryotes whose cell walls do not contain peptidoglycan
eukarya
domain of all organisms whose cells have nuclei, including protists, plants, fungi, and animals
domain
most inclusive taxonomic category; larger than a kingdom
bacteria and archaea
two unicellular prokaryotes
harsh
what kind of climate do archaebacteria live in?
protista, fungi, plantae, animalia
the domain eukarya is divided into what 4 kingdoms?
animal kingdom
this kingdom is multicellular, feed on plants or animals, and are ingestive heterotrophs `
plantae kingdom
this kingdom is multicellular, autotrophic, absorbs light to make glucose, cell walls made of cellulose
homologous structures, similar embryo development, molecular similarity in DNA, RNA, or amino acid sequence of proteins
list 3 ways in which modern taxonomy is used
protista kingdom
unicellular or multicellular, either autotrophic or heterotrophic, aquatic
fungi kingdom
multicellular except yeast, absorptive heterotrophs, cell walls made of chitin
absorptive heterotrophs
digest food outside their body and then absorb it
Linnaeus
known as the "Father of Taxonomy"
John Ray
was the first to use Latin for naming, botanist whose names were very long descriptions telling everything about the plant
methanogens
live in sewage treatment plants and reside in the archaea domain
chitin
the cell walls of fungi are made of what?
halophiles
live in salty conditions
dichotomous key
used to identify organisms, the characters are given in pairs and you read both characteristics and either go to another set of characteristics or identify the organism
Aristotle
this person first arranged organisms into plants and animals, then sub-divided them by their habitat
no
Have all the species on earth been identified?
13 billion
how many known species are there?
taxonomy
classification is also know as what?
eukaryotes
all organisms in the kingdoms protista, plantae, fungi, and animalia are what?
domain, kingdom, phylum, class, order, family, genus, species
list the 8 kingdoms in order
thermophiles
organisms that can live in high temperatures
