Brain Pop! Protists • https://www.brainpop.com/science/diversityoflife/protists/
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)
How are they classified? Protista = the very first Classification of Protists: • how they obtain nutrition (How they eat!) • how they move
We will be studying 4 types of protists: • Amoeba • Paramecium • Euglena • Volvox
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)
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/
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
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
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
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
