  • This is a great presentation. Is there a way I could have a copy--even a PDF to download? My school blocks Slideshare so I cannot just show this.

06 6 kingdoms and 3 domains

  1. 1. 3 Domains, 6 Kingdoms
  2. 2. Largest Smallest Taxonomic Levels Organisms can be classified animals beyond just genus and species. There are 8 levels of classification (taxa): Domain Kingdom Phylum Class Order Family Genus Species (the "domain" taxon is somewhat new and doesn't appear in all texts)
  3. 3. Taxonomic Levels These levels go from broad to specific.
  4. 4. Classification System Where you live, from broad to specific: - The Universe - The Milky Way Galaxy - Our Solar System - Earth - North America - Canada - Ontario - Toronto - Your address
  5. 5. Brown Bear Eukarya Animalia Chordata Mammalia Carnivora Ursidae Ersus arctos Taxonomic Levels
  6. 6. House cat Eukarya Animalia Chordata Mammalia Carnivora Felidae Felis catus Taxonomic Levels
  7. 7. Killer whale Eukarya Animalia Chordata Mammalia Cetacea Delphinidae Orcinus orca Taxonomic Levels
  8. 8. Wolf Eukarya Animalia Chordata Mammalia Carnivora Canidae Canis lupus Taxonomic Levels
  9. 9. Dog Eukarya Animalia Chordata Mammalia Carnivora Canidae Canis lupus Taxonomic Levels Dogs and wolves are of the same species and are often able to produce fertile offspring. However, since they are also still very different, scientists have created a subspecies for dogs: familiaris. Thus, the dog's full name is Canis lupus familiaris
  10. 10. Think. Pair. Share. How will you remember the names and order of the 8 taxonomic levels? Dear King Peter called out for good soup.
  11. 11. Think. Pair. Share. There are 6 Kingdoms. If you had to separate all life on Earth into 6 major categories, how would you do it?
  12. 12. Think. Pair. Share.Clues: Genus Salmonella Thermoplasma volcanium Genus Juniperus Family Leporidae Mould Genus Amoeba
  13. 13. The 6 Kingdoms: Eubacteria (Bacteria) Archaebacteria (Archaea) Protista Fungi Plants Animals
  14. 14. Review - Before We Go Further: What do these terms mean? Organic (biology definition) - Living or once-living matter. Autotroph - Makes its own food from inorganic sources. Heterotroph - Eats other organic matter. Eukaryote - Cells have a nucleus and other membranous organelles. Prokaryote - Cells have no nucleus and no membranous organelles.
  15. 15. Which Kingdom Does This Belong To? Family Leporidae
  16. 16. The 6 Kingdoms: Kingdom: Animalia Cell Type Eukaryote Cell Structure No cell wall Unicellular? No Multicellular? Yes Autotrophic? No Heterotrophic? Yes Reproduction Sexual (with exceptions)
  17. 17. Which Kingdom Does This Belong To? Mould
  18. 18. The 6 Kingdoms: Kingdom: Fungi Cell Type Eukaryote Cell Structure Cell walls with chitin Unicellular? Most Multicellular? Some Autotrophic? No Heterotrophic? Breaks-down organic matter Reproduction Sexual or Asexual
  19. 19. Which Kingdom Does This Belong To? Genus Salmonella
  20. 20. The 6 Kingdoms: Kingdom: Eubacteria Cell Type Prokaryote Cell Structure Cell walls often contain peptidoglycan Unicellular? Yes Multicellular? No Autotrophic? Some Heterotrophic? Some Reproduction Mostly asexual
  21. 21. Which Kingdom Does This Belong To? Thermoplasma volcanium
  22. 22. The 6 Kingdoms: Kingdom: Archaebacteria Cell Type Prokaryote Cell Structure Cell walls without peptidoglycan Unicellular? Yes Multicellular? No Autotrophic? Some Heterotrophic? Some Reproduction Asexual
  23. 23. Which Kingdom Does This Belong To? Genus Juniperus
  24. 24. The 6 Kingdoms: Kingdom: Plantae Cell Type Eukaryote Cell Structure Cell walls with cellulose; chloroplasts Unicellular? No Multicellular? Yes Autotrophic? Yes (with exceptions) Heterotrophic? No Reproduction Sexual or Asexual
  25. 25. Which Kingdom Does This Belong To? Genus Amoeba
  26. 26. The 6 Kingdoms: Kingdom: Protista Cell Type Eukaryote Cell Structure Cell walls with cellulose (some); chloroplasts (some) Unicellular? Most Multicellular? Some Autotrophic? Some Heterotrophic? Some Reproduction Sexual or Asexual
  27. 27. Think. Pair. Share. Eubacteria Archaea Protista Fungi Plants Animals There are 3 Domains. If you had to separate all 6 Kingdoms into 3 Domains, how would you do it? Life Eukarya Archaea Bacteria (Eubacteria) Kingdoms Domains
  28. 28. Classification Prokaryote Eukaryote Kingdoms Archaea Bacteria Protista Fungi Plantae Animalia Body Form unicellular unicellular unicellular or multicellular unicellular or multicellular multicellular multicellular Cell Wall present (different from bacterial cell wall) present (peptidoglycan) present in some present (chitin) present (cellulose) absent Mitochondria absent absent present present present present Nutrition (some or all systems) absorption, photosynthesis, chemosynthesis* absorption, photosynthesis, chemosynthesis* absorption, photo- synthesis, ingestion absorption photo- synthesis ingestion Nervous System absent absent absent absent absent present Motility present in some present in some present in some absent absent present Comparing the Six Kingdoms: Further Information *chemosynthesis is the use of inorganic carbon sources (like CO2 or CH4) for energy
