The Classification System An Interactive Power Point Presentation

The Classification System An Interactive Power. Point Presentation by Stacey Podolsky

The Classification System Why do scientists classify? – All living organisms have characteristics which distinguish them from nonliving objects – 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 broadest level of organization Kingdoms Monera Archaebacteria Protista Eubacteria Fungi Plantae Animalia

Monera u Prokaryotes – Cells lack a nucleus – Absorbs its own food u Some form chains or mats u 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 n Its members are very different from each other – Can be autotrophic or heterotrophic – Most are unicellular To view video Click on Paramecium § protozoa – some are multicellular § Seaweed n Eukaryotic – Its cells contain a nucleus www. microscopy-uk. org. uk/mag/articles/param 1. htm. http: //bio. rutgers. edu/~gb 101/lab 6_protists/r 6 a 2 param

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

Plantae o o Multicellular eukaryotes Autotrophs n Photosynthetic o 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
