  2. Use a simple classification key to identify an unknown organism. Key concepts/skills: Level 1: Define key vocabulary, explain binomial nomenclature. Level 2: Given a key, classify an unknown organism. Level 3: Describe levels of classification. Specifically differences between kingdoms( animal, plant, fungi, bacteria, protista) , characteristics of the common phylum (chordates) vertebrates and invertebrates, class (mammals),

  3. Use a simple classification key to identify an unknown organism. Key vocabulary: Classification classification key species vertebrates Taxonomy dichotomous key genus invertebrates Binomial nomenclature branching diagram mammals chordates

  4. Use a simple classification key to identify an unknown organism. I. Why classify A. Reasons 1. Communication 2. number of organisms 3. Aristotle’s system was confusing

  5. Use a simple classification key to identify an unknown organism. • Taxonomy – science of naming and grouping • organisms II. Binomial Nomenclature is naming organisms using two names A. Carolus Linneaus founded it in the 1700’s 1. Seven levels • Kingdom • Phylum • Class • Order • Family • Genus Scientific name • Species

  6. Use a simple classification key to identify an unknown organism. III. Dichotomous key A. Dichotomous Key – a series of choices which allows you to identify an organism based on its physical features.

  7. Use a simple classification key to identify an unknown organism. Examples

  8. Use a simple classification key to identify an unknown organism. B. Classification Key

  9. Use a simple classification key to identify an unknown organism. C.Branching Diagram

  10. Use a simple classification key to identify an unknown organism. IV. Specific Characteristics A. Mammals 1. bear live young, mammary glands, milk B. Vertabrates 1.have a bony layer around the spinal chord C. Invertabrates (no vertabrae) D. Chordates have centrally located spinal chord
