Taxonomy of Organisms 6.12 C
Taxonomy The branch of Science that formally names and classifies organisms by their structure, function and relationships.
Domains All forms of life are classified into 3 Domains. This based on their characteristics. It’s the BROADEST level of organization. They are…. Bacteria, Archaea & Eukarya
Kingdom Biologist have organized all living things into 6 large groups called Kingdoms. They are classified based on their specific characteristics. 6 Kingdoms: Archaea, Bacteria, Plant,Animal Fungi, and Protista
Domain: Archaea Kingdom: Archaea Bacteria Domain Archaea only has ONE Kingdom…Archaea bacteria. They come from EXTREME environments. Most die in the presence of oxygen. All organisms in the Archaea bacteria Kingdom must be: Unicellular Prokaryotic Autotrophic (Chemotrophs) Heterotrophic Asexual Reproduction
Domain: Bacteria Kingdom: Eubacteria Domain Bacteria only has ONE Kingdom…Eubacteria. They live in many different environments. Some need oxygen, but others die in the presence of oxygen. All organisms in the Eubacteria Kingdom must be: Unicellular Prokaryotic Heterotrophic Asexual Reproduction
Domain: Eukarya Kingdoms: Animal, Plant, Fungi, Protista This Domain contains the most Kingdoms…4 total. All of the Kingdoms contain organisms that are Eukaryotic. Hence the name Eukarya Domain. The 4 Kingdoms are: Plant Animal Fungi Protista
Domain: Eukarya Kingdom: Plant All cells have Nucleus and a Cell Wall. Ex: mosses, ferns, flowering plants, trees, bushes They are: Multicellular Eukaryotic Autotrophic Asexual and Sexual Reproduction
Domain: Eukarya Kingdom: Animal This kingdom is the one that you belong to. All organisms in this kingdom can be divided into vertebrates and invertebrates. Ex: insects, fish, humans, worms, starfish, dogs, cats, pig, dolphin They are: Multicellular Eukaryotic Heterotrophic Mostly Sexual Reproduction Very few Asexual Reproduction
Domain: Eukarya Kingdom: Fungi Some may confuse Fungi with Plants, but they are NOT plants. Fungi are decomposers, but like plants they do have a cell wall. Ex: Yeast, mold, mushrooms They are: Unicellular and Multicellular Eukaryotic Heterotrophic Asexual and Sexual Reproduction
Domain: Eukarya Kingdom: Protista Protista can be complicated. Some Protista in a dark environment are heterotrophic, but in light they are autotrophic. Ex: Amoeba, Euglena, Algae, Diatom, and Paramecium They are: Unicellular and Multicellular Eukaryotic Autotrophic and Heterotrophic Asexual and Sexual Reproduction
