The Classification System An Interactive PowerPoint Presentation by Stacey Podolsky

The Classification System Why do scientists classify? – –All living organisms have characteristics which distinguish them from nonliving objects – vi s so that organisms are easier to study –Scientists organize living things into groups so that organisms are easier to study

There Are Seven Levels of Classification 1.Kingdom 2.Phylum 3.Class 4.Order 5.Family 6.Genus 7.Species

The Five Kingdoms The Five Kingdoms The broadest level of organization Kingdoms Monera ArchaebacteriaEubacteria ProtistaFungiPlantaeAnimalia

Monera  Prokaryotes –Cells lack a nucleus –Absorbs its own food  Some form chains or mats  Bacteria, blue-green algae, and spirochetes –Over 10,000 known species

Monera Eubacteria and Archaebacteria –A growing number of researchers now divide this kingdom into 2 separate kingdoms Eubacteria –“The true bacteria” –Autotrophic and heterotrophic –Can cause: strep throat, used to produce yogurt, vitamins, etc. Archaebacteria –Autotrophic and heterotrophic –Live in: hot springs, on the ocean floor, salty water, your intestines

Video #1- Eubacteria E.coli Video contributed by Eric Knutsen

Protists Its members are very different from each other Its members are very different from each other –Can be autotrophic or heterotrophic –Most are unicellular  protozoa –some are multicellular  Seaweed Eukaryotic Eukaryotic –Its cells contain a nucleus To view video Click on Paramecium ml ml

Fungi Multicellular Eukaryotes Multicellular Eukaryotes Mushrooms Mold Mildew Unicellular Eukaryotes Unicellular Eukaryotes yeast

Plantae  Multicellular eukaryotes  Autotrophs Photosynthetic  They make their own food Mosses, ferns, woody and non-woody flowering plants

Animalia All are multicellular eukaryotes Heterotrophs They have their own means of locomotion

Dog Classification  Kingdom –Animalia  Phylum –Groups of classes  Chordata  Class –Groups of orders  Mammalia  Order –Groups of families  Carnivora

Dog Classification cont.  Family –Groups of species  Canidae  Genus –Groups of closely related species  Canis  Species –Groups of related organisms  Familiaris

There are 7 levels of Classification CORRECT! Back

CORRECT! Kingdom is the broadest level of organization. Back

CORRECT! Mushrooms, Mold and Mildew are examples of multicellular organisms. Back

CORRECT! All organisms in the ANIMALIA kingdom are multicellular eukaryotic organisms. Back

CORRECT! Eubacteria and Archaebacteria A growing number of researchers now divide the MONERA kingdom into 2 separate kingdoms Back
