Classification
Taxonomy is the science of naming and classifying organisms.
The 6 Kingdoms
History of the Kingdom System
1)1753 two kingdoms
3)1938 four kingdoms
2)1866 three kingdoms
4)1959 five kingdoms
5)1977 six kingdoms(monera deleted/bacteria and Archaea replace it)
Animalia Plantae Protista
Animalia Plantae Protista Monera
Animalia Plantae Fungi Protista Bacteria Archaea
Animalia Plantae Protista Monera Fungi
Animalia Plantae
1) Basic. Made by Carlus Linnaeus.
3) Herbert Copeland created this for prokaryotes (bacteria)
5) Carl Woese had monera split it into bacteria and Archaea because they have differences genetically and they have different types of cell walls.
4) Robert Whittaker created this for fungi because of how they eat (heterotrophs)
2) Ernest Hackel created this for single celled organisms.
The Swedish botanist Carlus Linnaeus created a system in the 1950’s that standardized the way organisms are classified and names.
Taxon is a level within the Linnaean system of classification that is organized into a nested hierarchy.Kingdom, phylum, class, order, family, genus, species
Binomial nomenclature is a naming system in which each species is given a two-part scientific name (genus and species) using Latin words.
Carl Woese had idea for three domains.
-Archaea- Single-celled prokaryotes that reproduce asexually, have distinct rRNA sequences, and have no cell walls. They live in earths most extreme environments and are often grouped according to where they live. -Bacteria- Single-celled prokaryotes that have a cell wall and live in all types of environments (including the human body). They reproduce by binary fission or budding. -Eukarya- Made up of all organisms that have eukaryotic cells.
Linnaean’s system does not classify organisms at the molecular level so the system might classify two animals together because of similar traits when really they might not be related at all.
Scientific names allow scientists around the world to talk about particular species and organisms without confusion.
Bacteria Single-celled prokaryotes that have a cell wall and live in all types of environments (including the human body). They reproduce by binary fission or budding.
Fungi Are eukaryotic, heterotrophic, and usually multicellular (but some are single celled) organisms with thick cell walls usually composed of chitin. They obtain their nutrients though absorption and often function as decomposers.
Protista Mostly single-celled but sometimes multicellular or colonial. Many resemble plants, animals, or fungi but are simpler in structure. Animal-like protists are unicellular, heterotrophic, and most can move. Plantlike protists have no roots, stem, or leaves but many are photosynthetic autotrophs. Funguslike protists are mostly decomposers that can move during part of their life cycle.
Animalia Are multicellular, eukaryotic heterotrophs with cells that have cell membranes not cell walls. Most of the cells are organized into tissues and most animalia reproduce asexually.
Plantae Are multicellular photosynthetic autotrophs that have mostly adapted to life on land and have thick cell walls made of cellulose.
Archaea Single-celled prokaryotes that reproduce asexually, have distinct rRNA sequences, and have no cell walls. They live in earths most extreme environments and are often grouped according to where they live.
