What is taxonomy?
study of classifying organisms.
What is a taxonomist? What is a taxon?
scientists who study classifying; (taxa=plural) a category into which realted organisms are placed.
What are the six reasons of classification?
Every Nautical Plant Likes Dirt Raw=
1(shows)Evolutionary relationships
2 Names organisms
3 prevents misnomers
4(same) language/Latin
5 (prevents) Duplicated names
6 Rules for naming
Who was the first taxonomist to divide organisms into land, sea, and air dwellers?
Aristotle.
Who developed the system of binomial nomenclature
Linnaeus.
How do you write a scientific name?
With the genus capitilized and the species in lower case, either underlined or italicized in print. The genus can be abbreviated, but not the species.
What is morphology?
Similar structure and function in an organism; used by Linnaeas to place organims in taxa.
What were Linneaus's two kingdoms?
Animalia and Plantae
What are the 6 taxa called?
Kingdom
Phylum/Division
Class
Order
Family
Genus
species
(every capitilized except species)

(King Phillip Came Over For Green Soup)
How are plants and bacteria subdivided?
Plants=varieties
Bacteria=strains
What are homologous structures?
same structure, different function; show common ancestory.

ex. human's arm v. penguin's flipper v. a bat's wing.
What are analogous structures?
same function, different structure; do not show a close relationship.

ex. insect wing v. bird wing
What are the six kingdoms of modern taxonomy?
Archaebacteria
Eubacteria
Protista
Fungi
Plantae
Anamalia

Ants
Eat
Pumpkin
Flavored
Pants
All the time!
Which kingdoms are unicellular prokaryotes and lack a nucleus?
Archaebacteria and Eubacteria
How do fungi obtain energy (eat)?
By obsorbing nutrients b/c they are herterotrophs.
Where do archaebacteria live?
harsh enviroments; salty lakes, intestines of mammals, sulfur springs etc
Are archaebacteria autotrophs or heterotrophs?
both.
Are Protista heterotrophs or autotrophs? Unicellular or multicellular?
both heterotrophic(ameba) and autotrophic(euglena); mainly unicellular/few multicellular.

What is phylogeny?
the evolutionary history/development of multiple organisms.
What are phylogenic trees?
branching diagrams showing how organisms are related evolutionally, based on fossil records. Also called family trees
What is at the base of a phylogenic tree? At the tips of the branches?
a common ancestor! the most modern organisms!
What happened when a branch divides into a smaller branch?
a new species evolves!
What does a cladogram show?
how organisms are realted based on shared, derived characteristics.
ex. feathers, hair, scales
What is the Three Domain system?
a system dividing organisms into three groups based on the similaritites in thier RNA sequences.
What are the Three Domains called?
Bacteria (Eubacteria), Archaea (Archaebacteria), and Eukarya (eukaryotes/Protista, Fungi, Plantae, Animalaia)
