  1. Diversity of Living Things UNIT 2: MICROBIOLOGY

  2. 2.1 Taxonomy pg. 98 - 101 Definition: • science of classifying organisms (both living & extinct) Purpose of Taxonomy Why do we classify living organisms? • to identify organisms • to represent evolutionary relationships among them

  3. Taxonomic System • developed by Carl Linnaeus (1707-1778) in Latin • based his classification on structural and physical features • the more features organisms have in common, the closer their relationship

  4. Binomial Nomenclature(common worldwide language) • the scientific name of a species is formed by the combination of • Genus(always capitalized) (can be written alone) Example: Ursus = all bears 2. species(lowercase) (can never be written alone) Example: Ursusamericanus = North American Black Bears note: both are italicized two terms:

  5. Species a group of organisms with similar features that can interbreed and produce fertile offspring SPECIES: = + horse donkey mules

  6. Binomial Nomenclature Examples 1 2 3

  7. Kingdom Phylum Class Order Family Genus Species 7 Levels of Classification Largest / General Smallest / Specific

  8. Katie please come over for ginger snaps Kids playing with cars on freeways get squashed Kids prefer cheese over fried green spinach King Philip came over from Greater Spain King Phillip called out for good soup King Philip came over for good spaghetti Kings play chess on funky green stools Kings possess crowns of fine gem stones Kissing people carries over fungus, germs & spit Acronym for theLevels of Classification

  9. Make your own saying! • K • P • C • O • F • G • S

  10. Levels of Classification

  11. Taxonomic Classifications Gorillas & Chimps have 98% same DNA as us

  12. Dichotomous Key • two-part key used to identify living things • a series of choices must be made • each choice leads to a new branch of the key • end result is the name of the organism being identified

  13. Homework • Homework: Text • Page 101 # 1 – 7 • Activity 2.2 a - d (use figure 9 and Not 10 for part d)

  14. Dorsal side first dorsal fin caudal fin second dorsal fin gill slits anal fin pelvic fin pectoral fin Ventral side SHARK ANATOMY
