|
the science of describing, naming, and classifying organisms
|
|
taxon
|
any particular group within a taxonomic system
|
|
kingdom
|
made up of only 2 kingdoms (animal and plants)
|
|
domains
|
categories above the kingdom level
|
|
phyla
|
subsets below the kingdom level
|
|
classes
|
each phylum consists of classes
|
|
orders
|
each class contains orders

|
|
binomial nomenclature
|
the system of two-part names
|
|
subspecies
|
variations of a species that live in different geographic areas
|
|
systematics
|
the goal is to classify organisms in terms of their natural relationships

|
phylogentics
|
the analysis of the evolutionary or ancestral relationships among taxa
|
|
phylogentic diagram
|
a way systematists represent their hypothesis
|
|
cladistics
|
a system of phylogentic analysis that uses shared and derived characters as the only criteria for grouping taxa
|
|
shared character
|
a feature that all memebers of a group have in common, such as hair in mammals or feathers in birds
|
|
derived character
|
a feature that evolved only within the group under consideration; for example, feathers are thought to be a derived character for birds

phylogentic diagrams
|
|
bacteria
|
this domain is made up of small, single-celled prokaryotic organisms that usually have a cell wall and reproduce by cellular fission
|
|
archaea
|
this domain consists of prokaryotes and have distinctive cell membranes and other unique biochemical and genetic properties
|
|
eukarya
|
the most familiar groups of organisms that consist of eukaryotic organisms
|
|
eubacteria
|
this kingdom aligns with the bacteria domain
|
|
archaebacteria
|
this kingdom aligns with the archaea domain
|
|
protista
|
one of the four kingdoms of eukaryotes and has been defined as those eukaryotes that are not plants, animals, or fungi
|
|
fungi
|
the second kingdom of eukaryotes that consists of eukaryotic, heterotrophic organisms that are unicellular or multicellular and that gain nutrients in a unique way
|
|
plantae
|
the third kingdom of eukaryotes which consists of eukarytoic, multicellular plants
|
|
animalia
