  1. ClassificationBiologists have estimated that there are many trillions of organisms on our planet. We need to classify or sort them into groups to help us study them.

  2. Classification Biologists work with a system of five kingdoms. The key differences between kingdoms relate to whether the organisms are unicellular or multicellular, how the organisms obtains their food (nutrition), and whether they are mobile or not (movement).

  3. 5 Kingdoms • Organisms are put into one of the kingdoms because of difference in movement, nutrition and cell structure.

  4. 5 KINGDOMS

  5. KINGDOM MONERABacteria • Unicellular organisms with a cell structure different to all other living organisms. • Do not have a nucleus. • Extracellular digestion • Decomposers • Use flagella for movement

  6. KINGDOM PROTISTA • (Usually) Single celled organisms but their cells are more like plant and animal cells because they have a nucleus. • Everything that doesn’t fit easily into the other four groups ends up here! • Examples: euglena, paramecium, amoeba • Some carry out photosynthesis.

  7. KINGDOM FUNGI • Fungi are a huge group that can be as little as a single celled yeast. • Yeast are used to brew beer, make wine and rise bread. Some fungi are huge (eg. Mushroom). • Fungi reproduce using spores and they have a nucleus. • Extracellular digestion • Decomposers

  8. KINGDOM PLANT • Multicellular with nucleus. • Immobile but parts move towards water (roots) or sunlight(shoot). • Producers as they make their own food.

  9. KINGDOM ANIMAL • Multicellular with nucleus. • Moving bodies and parts • Internal digestion of food • Consumers (=cannot make their own food)

  10. Compare and contrast: Plant and Animal Kingdom

  11. Compare and contrast: Plant and Fungi Kingdoms

  12. classification levels Related species are put into a genus. Similar genera are put into a family. Similar families are put into an order. Similar orders are put into a class. Similar classes are put into a phylum, and finally related phyla go into a kingdom.

  13. Kingdom Phylum Class Order Family Genus Species

  14. Binomial System • An organism’s classification should include a clear description, an accurate diagram, and its unique name (denoted by the genusand species).

  15. Scientific name: Common name:Short tailed bat Mystacinatuberculata GENUS SPECIES
