A protist is… Protists belong to the Kingdom Protista, which includes mostly single-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 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 flagella for movement http://www.youtube.com/watch?v=He9FSeGRi3A&feature=related
