  1. Classification

  2. How many species??? • Each year, researchers report more than 15,000 new species • They estimate there are 8.7 million species on the planet, plus or minus 1.3 million

  3. Taxonomy • Branch of biology that groups and names organisms based on studies of their different characteristics.

  4. The Diversity of Life has Unity • All living things have cell • All living things have DNA or RNA

  5. Carolus LinnaeusFather of modern taxonomy

  6. Rules of Binomial Nomenclature Genus • First Word • Capitalized • Underlined or italicized • Ex. Acer or Acer

  7. Rules of Binomial Nomenclature Specific Epithet (species) • Second Word • Lower case • Underline or italicized • Ex. lubricoides or lubricoides

  8. Examples • Homo sapiens • Homo sapiens • If you are writing it by hand it MUST be Underlined

  9. Taxon’s • categories of organisms grouped by similar characteristics • Kingdoms – broadest category (6 kingdoms currently) • Species – most specific category

  10. Species –organism that can reproduce and create viable offspring • Viable means offspring that can also reproduce • Exceptions- mule or zebroid

  11. Classification levels

  12. You are responsible for learning this chart

  13. Pneumonic device to learn classification system and human Kings Play Cards On Fridays Generally Speaking Kevin Please Come Over For Great Soup You may use one of these or make you own

  14. Create one for the classification of Man A___________ C___________ M___________ P___________ H___________ H___________ S____________

  15. Which to organisms are closer related???

  16. Taxonomy Started out with 2 categories Plant or Animal

  17. HAD A 3 -> 4 -> 5 -> NOW USE A 6 Kingdom system of Classification • 1 – Eubacteria • 2 – Archeabacteria • 3 – Protista • 4 - Fungi • 5 - Plant • 6 – Animal • It may change to an 8 or 12 kingdom but right now it remains a 6 kingdom system

  18. Eubacteria • Bacteria that live in extreme environments • Prokaryotes • Examples Swamps, hydrothermal vents, seawater evaporating ponds

  19. Archeabacteria • all other types of bacteria • Prokaryotes • Most are harmless but some may cause disease

  20. Protista • Eukaryotes • Characteristics of both plant and animal • Examples algae, protozoa, and slime molds

  21. Fungi • Eukaryotes • No chlorophyll cannot make own food • Heterotrophs • Mushrooms

  22. Plantae • Multicellular eukaryotes • Photosynthetic • Nonmotile

  23. Animalia • Multicellular eukaryotes • Heterotrophs • Usually mobile • Most have a nervous system
