Protists

Learn about protists, the organisms that don't fit into other kingdoms. Explore the characteristics, movement, nutrition, and interesting facts about Amoeba, Paramecium, Euglena, and Volvox. Use the provided Middle School Chart and Brain Pop resources for a comprehensive understanding.

  3. Brain Pop! Protists • https://www.brainpop.com/science/diversityoflife/protists/

  4. A protist is… • Protists belong to the Kingdom Protista, which includesmostlysingle-celled organisms that do not fit into the other kingdoms. Characteristics of Protists: • mostly unicellular, some are multicellular (algae) • most live in water (though some live in moist soil or even the human body) • ALL are eukaryotic (have a nucleus)

  5. How are they classified? Protista = the very first Classification of Protists: • how they obtain nutrition (How they eat!) • how they move

  6. We will be studying 4 types of protists: • Amoeba • Paramecium • Euglena • Volvox

  7. Protist Name: Amoeba • Movement: An amoeba Moves using “false feet” or pseudopodia • Nutrition: Eats food by surrounding and engulfing it • Does not make its own food (heterotroph) • Interesting Facts: • Many are parasites (Brain Eating Amoeba)

  8. Video Clips • Movie of an amoeba eating: http://www.youtube.com/watch?v=ojrkxmD6tT8 • Movie of an amoeba moving: http://www.youtube.com/watch?v=7pR7TNzJ_pA&feature=fvwp • Brain Eating Amoeba: http://www.animalplanet.com/tv-shows/monsters-inside-me/videos/the-brain-eating-amoeba.htm • http://www.usatoday.com/videos/news/usanow/2013/09/12/2804833/

  9. Protist Name: Paramecium • Movement: Moves using hair-like Cilia • Nutrition: Ingests through a mouth pore • Stores food in food vacuole • Releases waste through an anal pore • Heterotroph like the amoeba • Interesting Facts: Has two nuclei; more developed structures • Paramecium moving & eating: http://www.youtube.com/watch?v=zS0f82ZJtvk&feature=related

  10. Protist Name: Euglena • Movement: Has whip-like flagellum for movement • Nutrition: • Has chloroplasts to produce food through photosynthesis (autotrophic) • Can also surround & engulf food • Movement: Has whip-like flagellum for movement • Interesting Facts: • Characteristics of both plants & animals • Has a light sensitive eye spot • Video of Euglena: http://www.youtube.com/watch?v=ZHZZKwrYm4g

  11. Protist Name: Volvox • Interesting Facts: • A type of algae • Actually form large spherical (like a ball) colonies of single-celled organisms • AS MANY AS 50,000 in one colony! • Although they are all individual organisms, they work together to act like one multicellular organism

  12. Volvox • Nutrition: Can digest food (heterotroph) as well as produce their own food through photosynthesis (autotroph) • Movement: Have flagellafor movement • http://www.youtube.com/watch?v=He9FSeGRi3A&feature=related
