The levels of classification | Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species |
Binomial Nomenclature | Organisms are commonly referred to according to the two most specific taxonomic levels: genus and species, which are often Latin. |
Taxonomist | A scientist that studies taxonomy and use the classification system to identify and name organisms are taxonomists. |
The 3 domains for classification | Bacteria, Archaea, and Eukarya |
Bacteria | This domain consists of unicellular prokaryotes. They lack a cell nucleus and membrane-bound organelles, but they are surrounded by a thick cell wall. |
Archea | Made up of unicellular prokaryotes that also have a cell wall but differ in composition from bacteria. Archaean cell walls lack the substance peptidoglycan found in bacteria. Archean organism can also survive at extreme temperatures. |
Eukarya | This domain differs from the others because its membersā cells contain a nucleus and membrane-bound organelles. |
The Four Kingdoms of Eukaryotes | Protista, Plantae, Fungi, and Animalia. |
Protista | These ancient eukaryotes have some characteristics not shared by many other members of the domain, including the fact that many are unicellular. Even within the kingdom there is great diversity. |
Plantae | The Eukaryotic Kingdom mostly made up of plants which are multicellular autotrophs that photosynthesize for their energy. All members of this kingdom have the same basic parts including roots, stems, and leaves/ |
Fungi | Fungi are multicellular, although yeasts a type of fungi are unicellular. Like plants, the cells of fungi have a cell wall. Fungi, however, cannot produce their own food through photosynthesis, so they are called heterotrophs. |
Animalia | Animalia is quite diverse. In addition to humans, it includes birds, fish, insects, and a wealth of other animals. What they all have in common is that animals are multicellular, are heterotrophic, and have cells lacking a cell wall. |
