3. Brain Pop! Protists

4. 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)

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)

Brain Eating Amoeba:

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:

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
Interesting Facts:
Characteristics of both plants & animals
Has a light sensitive eye spot
Video of Euglena:

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 flagella for movement
