Animala
Classification kingdom containing complex multicellular organisms
Archaea
prokaryotes (most of which are known to live in extreme environments)
Archaebacteria
kingdom made up of prokaryotes (most of which are known to live in extreme environments) that are distinuished from other prokaryotes
Bacteria
in a modern taxonomic system, a domain made up of prokaryotes that usually have a cell wall and that usually reproduce
binomial nominclature
system for giving each organism a two word name
biodiversity
the variety of organisms in a given area, the genetic variation within a population
clade
taxonomic grouping that includes only a single ancestor
cladistics
phylogenetic classification system that uses shared derived characters
cladogram
diagram that is based on patterns of shared derived traits
class
taxonomic category containing orders with common characteistics
derived character
feature that evolved only within a toxonomic group
division
-in taxonomy, a grouping of similar classes of plants
Domain
in a taxonomic system based on rRNA analysis, one of the three broad groups that all living things fall into
euebacteria
1. in a traditional taxonomic system, a kingdom made up of all prokaryotes except members of the kingdom Archaebacteria; currently, biologists prefer to classify members of this kingdom into the domain Bacteria
eukarya
in a modern taxonomic system, a domain made up of all eukaryotes; this domain aligns with the traditional kingdoms Protista, Fungi, Plantae, and Animalia
family
the taxonomic category below the order and above the genus
fungi
classification kingdom made up of nongreen, eukaryotic organisms that get food by breaking down organic matter and absorbing the nutrients, reproduce by means of spores, and have no means of movement
genus
the level of classification that comes after family and that contains similar species
kingdom
the highest taxonomic category, which contains a group of similar phyla
order
the taxonomic category below the class and above the family
phylogenetic diagram
branching diagram that models the relationships by ancestry between different species or other taxonomic groups
phylogenetics
the analysis of evolutionary, or ancestral, relationships between taxa
phylum
-the taxonomic group below kingdom and above class
plantae
classification kingdom made up of eukaryotic, multicellular organisms that have cell walls made mostly of cellulose, that have pigments that absorb light, and that supply energy and oxygen to themselves and to other life-forms through photosynthesis
protista
mostly one-celled eukaryotic organisms that are different from plants, animals, and fungi
speial character
feature that is shared by all members of a particular group of organisms
species
group of organisms that are closely related and can mate to produce fertile offspring; also the level of classification below genus and above subspecies
sub species
- taxonomic classification below species that groups organisms that live in different geographical areas, differ morphologically from other populations of the species, but can interbreed with other populations of the species
systematics
the classification of living organisms in terms of their natural relationships; it includes describing, naming, and classifying the organisms
taxon
any particular group within a taxonomic system
taxonomy
the science of describing, naming, and classifying organisms
