  1. Classification

  2. Classification • The process of grouping things based on their similarities.

  3. What do you think? • What are some things that you classify on a daily/weekly basis? • What kinds of things do you think scientists classify?

  4. Nom- • Latin for “A Name” • Cognomina – noun – a nickname

  5. Taxonomy • Study of how living things are classified • Knowing an organisms classification tells you a lot about its characteristics • Crow – bird – flies, has feathers, wings, hollow bones • Frog – amphibian – thin skin, lays eggs in water, double life

  6. Binomial Nomenclature • Carolus Linnaeus – 1750s • Grouped organisms based on observable features • Two-part scientific name: • binomial nomenclature – “two names”

  7. Genus and Species • Genus – a group of closely related organisms • Felis – domestic cats, jungle cat, sand cat • Canis – wolves, dogs, and dingos • Gallus – chickens and pheasants

  8. Species – a group of organisms that can mate and produce fertile offspring Horse + donkey = mule Mule + mule ≠ mule – therefore a horse and a donkey are not the same species Lion + tiger = liger Liger + liger ≠ liger therefore a lion and a tiger are not the same species

  9. Binomial NomenclatureTwo-part naming system • Genus species • Genus is in capitalized • Species is lower case

  10. Why use two parts?

  11. Why use latin and greek roots?

  12. Levels of Classification • Kingdom • Phylum • Class • Order • Family • Genus • Species

  13. A way to remember • King • Phillip • Came • Over • For • Good • Soup

  14. The more levels that two organisms share, the more characteristics they have in common • They are usually more closely related as well.

  15. What is the smallest taxonomic group that they all share? • What traits do you think that they share? • How are they different? • What is the largest taxonomic group that they all share? • What is the correct scientific name for each one?

  16. What is the smallest taxonomic group that they all share? • What traits do you think that they share? • How are they different? • What is the largest taxonomic group that they all share? • What is the correct scientific name for each one?

  17. What is the smallest taxonomic group that they all share? • What traits do you think that they share? • How are they different? • What is the largest taxonomic group that they all share? • What is the correct scientific name for each one?

  18. What is the smallest taxonomic group that they all share? • What traits do you think that they share? • How are they different? • What is the largest taxonomic group that they all share? • What is the correct scientific name for each one?

  19. Kingdom Phylum Class Order Genus Species Family

  20. House cat • Platypus lion Ability to purr Brown Bear Retractable claws Placenta Hair and mammary glands

  21. Hibiscus • Moss Pine tree Flowers Fern seeds Vascular tissue Ability to live on land

  26. Domains and Kingdoms • Placement based on • Cell wall – yes/no – what is it made of? • cell type • Prokaryote – no nucleus or organelles • Eukaryote – nucleus and organelles • ability to make food • Autotroph -self -feeder - producer - photosynthesis • Heterotroph– other feeder - consumer • number of cells in their body • Unicellular • Multicellular

  27. 3 Domains and 6 Kingdoms • Domain Archaea • Archaebacteria • Domain Bacteria • Eubacteria • Domain Eukarya • Protista • Fungi • Plantae • Animalia
