Science of classifying and naming organisms |
Taxonomy |
|
|
Level within the Linnaean system of classification (Kingdom, Phylum, Class, Order, Genus, Species) |
Taxon |
|
|
Naming system used in which each species is given a two-part scientific name from the genus and species using Latin words |
Binomial nomenclature |
|
|
First name in binomial nomenclature, the second-most specific taxon in in the Linnaean classification system that includes one or more physically similar species, which are thought to be closely related |
Genus |
|
|
Evolutionary history of a group of related species |
Phylogeny |
|
|
Method of organizing species by evolutionary relationships in which species are grouped according to the order that they diverged from an ancestral line |
cladistics |
|
|
Diagram that displays proposed evolutionary relationships among a group of species |
Cladogram |
|
|
Trait that differs in structure and function from that found in the ancestral line for a group of species; used in creating a cladogram |
Derived character |
|
|
One of the three domains of life; containing single-celled prokaryotes in the kindgom Eubacteria |
Bacteria |
|
|
One of the three domains of life; containing single celled prokaryotes in the kingdom Archaebacteria |
Archae |
|
|
One of the three domains of life; containing all the eukaryotes from the kingdoms Protista, Fungi, Plantae and Animalia |
Eukarya |
|
|
Eukaryote that is not an animal, plant or fungus |
Protist |
|
|
Animal-like protists |
Protozoa |
|
|
Temporary extensions of cytoplasm and plasma membrane that helps protozoa move and feed |
Pseudopod |
|
|
Short hair-like projections that cover some or all of the cell surface and help the organisms swim and capture food |
Cilia |
|
|
Photosynthetic plant-like protists |
Algae |
|
|
Eukaryotic, heterotrophic, usually multicelluar but some are single-celled; thick cell walls made of chitin, obtain nutrition through absorption; often function as decomposers |
Fungi |
|
|
Ecological relationship between the mycelium of fungus and the roots of certain plants |
Mycorrhizae |
|
|
Fungus that grows symbiotically with algae, resulting in a composite organism that grows on rocks or tree trunks |
Lichen |
|
|
Protist with slimelike amoeboid stage that grows on decaying vegetation and in moist soil |
Slime mold |
