  1. The 7 Levels of Classification

  2. Kingdom • 5 kingdoms • Based on ability to make food and number of cells in their body • Largest level

  3. The 5 Kingdoms

  4. Monerans • Single-celled • Absorb nutrients • Ex. Bacteria

  5. Protists • Single-celled or multi-cellular • Absorb nutrients or “eat” • Ex. paramecium, amoeba, and kelp

  6. Fungi • Single-celled or multi-cellular • Get nutrients from absorbing the surface they are on • Ex. Mushroom, grain mold, penicillin

  7. Plants • Multi-cellular • Get energy from the sun • Ex. ferns, trees, grasses

  8. Animals • Multi-cellular • Eat other organisms • Ex. Humans, bears, fish, frogs, butterflies, and starfish

  9. Phylum K P C O F G S • Breaks down a Kingdom into smaller categories • If 2 organisms are in the same phylum- they are also in the same Kingdom

  10. Phylum c) In the plant kingdom these are called divisions - 2 groups are vascular and non-vascular

  11. Phylum d) In the animal kingdom there are 35 different phyla – 2 groups vertebrates and invertebrates

  12. Class K P C O F G S • Breaks down a phylum into smaller categories

  13. Order K P C O F G S • Breaks down a class into smaller categories

  14. Family K P C O F G S • Breaks down an order into smaller categories

  15. Genus K P C O F G S • Contains closely related organisms • First word in the scientific name

  16. Species K P C O F G S • Same type of organism able to breed and produce young of the same kind • The second word in the scientific name

  17. Classification System - The study of classification is called taxonomy.

  18. Classification System • Organisms are placed in a broad group and then more specific groups. • The more classification levels organisms share, the more characteristics they have in common

  19. Classification System - Groups of organisms become smaller as you move from Kingdom to Species - Organisms are more closely related if they share more classification levels

  20. Scientific Name • Genus species • Written in italics. • Genus is capitalized, species lower case • Ex. Canis lupus is a wolf
