classification

taxonomy

Branch of science that names, identifies, and groups organisms based on a set criteria

what is the first part for bionmial nomenclature

genus name

what is the second part for bionomial nomenclature

specific epithet

what are the 4 rules in writing a scientific name?

1. first letter is also capitalized in a genus name but the rest of the genus name and all the others are lowercase

2. If a specific name is written in a printed book then it should be italicized

3. When a scientific name is written by hand both parts of the name should be underlined

4. after written complete, the genus name will be abbreviated to the first letter in later appearance

biologists try to organize, or classify, living and fossil species into larger groups that have biological meaning. Biologists often refer to these groups as

\

taxa or taxon

The science of naming and grouping organisms is calle

systematics

what are the taxonomic categories in broadest to most specific

domain

kingdom

phylum

class

order

family

genus

species

A group of organisms that can interbreed and produce fertile offspring

species

is the next higher taxon, consisting of similar, related genera.

family

what is the goal of systematics?

is to organize living things into groups that have biological meaning.

are prokaryotes whose cell walls contain peptidoglycan. Eubacteria are a diverse group that can survive in many different environments.

Eubacteria

Domain Archaea

Archaea are thought to be more ancient than bacteria and yet more closely related to our eukaryote ancestors.

Domain Eukarya

Domain Eukarya contains Kingdom Protista, Kingdom Fungi, Kingdom Plantae, and Kingdom Animalia

Kingdom Bacteria

uDyes added to the bacteria identify those with and those without an outer layer of lipid

uFlagella help prokaryotes to move toward materials that they need to survive

uContain peptidoglycon

Two prokaryotes attach to each other and exchange genetic information.

Conjugation

Goal of bionomial nomentclature

ueach species is assigned a two-part scientific name.

eukaryotic organisms that can be unicellular, colonial, or multicellular.

protists

what are the 6 kingdoms

Animal, Plant, Protist, Fungi, Bacteria, Archaea

Aristotle classification theory

He categorized them as either animals or plants

animals were classified according to the presence or absence of red blood

plants were classified by average size or structure

Lannaeus classification theory

came up with a two-word naming system (binomial nomenclature)

Identified and grouped organisms based on a set of criteria known as taxonomy

First part genus name and second name is specific epithet
