  1. Biology Core 9. Differentiate between the previous five-kingdom and current six-kingdom classification systems. Objective B.9.5: Differentiate among the major characteristics of the six kingdoms. Additional content to be taught: Identifying ways in which organisms from the Monera, Protista, and Fungi kingdoms are beneficial and harmful Examples: beneficial—decomposers, harmful—diseases • Writing scientific names accurately by using binomial nomenclature 11. Classify animals according to type of skeletal structure, method of fertilization and reproduction, body symmetry, body coverings, and locomotion. Examples: reproduction—sexual, asexual; locomotion—cilia, flagella, pseudopodia Objective B.11.2: List types of body coverings and locomotion found in animals. Objective B.11.5: Describe the types of reproduction as asexual or sexual..

  2. Protists

  3. Six-Kingdom System Animalia Plantae Fungi Protista Archaebacteria Eubacteria

  4. Protists The Outcasts

  5. Protists • All Eukaryotic • All live in moist environments Three Subcategories: Some unicellular Others multicellular Animal-like Some heterotrophs Others autotrophs Some microscopic Others 300 feet long! Plant-like

  6. Protozoans Animal-like Protists • All unicellular • All heterotrophic Subdivided: Mode of Locomotion Pseudopodia Cilia Flagella

  7. Animal-like Protists with Pseudopodia • They move by extending a part of their body forward, and pulling the rest of its body behind it • Pseudopodia – finger-like projections that extend outward - Also used to trap food Amoeba

  8. Animal-like Protists "Ciliates" with Cilia • They move by beating tiny hair-like structures called cilia • The cilia act as tiny oars that allow the protist to move through its watery environment Paramecium

  9. Animal-like Protists "Zooflagellates" with Flagella • They move by beating their long whip-like structures called flagella. • May have one or more flagella • Some are parasitic and cause diseases Giardia Tsetse Fly Diarrhea Trypanosoma African Sleeping Sickness

  10. Another Disease-causing Protozoan... Female Anopheles mosquito Plasmodium falciparum Malaria

  11. All autotrophic Plant-like Protists • Produce oxygen • Form the base of aquatic food chains Four basic groups: • Can be unicellular, multicellular, or live in colonies Euglenoids Dinoflagellates Diatoms Algae

  12. Plant-like Protists Algae • Green in color Green Algae • Mostly unicellular, but some form colonies, and a few are multicellular • Live in freshwater, salt water, and a few live on land Volvox

  13. Protist Quiz

  14. 1. What is the name of this organism to the left? 2. What is this structure called? 3. Describe how this organism moves (locomotion). 4. Identify this organism to the right. 5. What are the structures located around its body called? 6. Describe this organisms mode of locomotion.

  15. 7. What are these structures called? Giardia 8. Describe this organism’s mode of locomotion. These three organisms can be harmful to humans. 9. Which protist causes malaria? Plasmodium Trypanosoma 10. Which protist often causes diarrhea? 11. Which protist causes African Sleeping Sickness?

  16. Bonus! Name the insects that carry and transmit these disease-causing protists. A. B.

  17. The End
