Presentation Transcript

  1. Classification Modified By Ms. Hundley

  2. The science of classifying organisms is called taxonomy • The “father of modern taxonomy” was Carolus Linnaeus (Carl von Linné) • Organisms are grouped into “taxa” based on their similarities to each other 1707-1778

  3. Old System • 5 Kingdom Classification System: • Monera: all prokaryotes • Protista: single-celled eukaryotes (protists) • Fungi: multi-cellular heterotrophic sessile eukaryotes • Plantae: multi-cellular autotrophic sessile eukaryotes • Animalia: multi-cellular heterotrophic motile eukaryotes

  4. 6 Kingdom Proposal Archebacteria Eubacteria

  5. New Classification • Organisms are grouped into smaller and smaller groups all the way down to their species • A species is the most specific grouping and includes only organisms that can interbreed with each other and produce fertile offspring

  6. King Philip Came Over For Gold Specks

  7. Ursus americanus American Black Bear

  8. Often Latin names contain clues about the type of organism being described.CanisdomesticusAnd closely related organisms are often in the same genus, also giving clues about their namesCanis lupusSome names are given after the discoverer, or the discovery location, or even a Latinized descriptive term in English

  9. Domain Archaea

  10. Domain Eubacteria

  11. Domain Eukarya

  12. Kingdom Protista Animal-Like (Protozoans) Paramecium Giardia Amoeba Fungus-Like Plant-Like Water Mold Slime Mold Diatom Euglena Green Algae Brown Algae Dinoflagellates

  13. Kingdom Fungi

  14. Kingdom Plantae Primitive Plants Bryophyte (Moss) Pteridophyte(Fern) Complex Plants Pteridophyte(Fern) Coniferophytes (Pine Trees) Angiosperm; Dicot Angiosperm; Monocot

  15. Porifera Ctenophora Cnidaria Nematoda Platyhelminthes

  16. Chordata Arthropoda Annelida Molluska Echinodermata

  17. Human Classification

  18. Human Classification Domain: Eukarya Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Primates Family: Hominidae Genus: Homo Species: Sapien

  19. Dichotomous Keys 1a. Organism has 4 legs Go to # 2 1b. Organism has more than 4 legs Go to # 20 2a. Organism has a tail Go to # 3 2b. Organism has no tail Go to # 35 3a. Organism has stripes Bengal Tiger 3b. Organism has no stripes African Lion

  20. Dichotomous Key • Try this one: 1a. Organism walks on all 4 legs (quadruped) 2 1b. Organism walks on 2 legs (biped) 8 2a. Organism has visible fur 3 2b. Organism has no visible fur 20 3a. Organism lives in warm climates 7 3b. Organism lives in cold climates 4 4a. Organism has brown or black fur Ursus americanus 4b. Organism has white fur Ursus maritimus
