Interesting Facts

3. A protist is… (write down the stuff in blue in your science notebook)
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)

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

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

6. Amoeba An amoeba Moves using “false feet” or pseudopodia
Eats food by surrounding and engulfing it
Does not make its own food (heterotroph)

7. Paramecium Moves using hair-like Cilia Has two nuclei
Ingests through a mouth pore
Stores food in food vacuole
Releases waste through an anal pore
Heterotroph like the amoeba

8. Euglena Characteristics of both plants & animals
Has chloroplasts to produce food through photosynthesis (autotrophic)
Has light sensitive eye spot
Can also surround & engulf food
Has whip-like flagellum for movement

9. Volvox
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
Can digest food (heterotroph) as well as produce their own food through photosynthesis (autotroph)
Have flagella for movement

10. Test Corrections…Due WED!
Please make corrections on your test in a different color ink.
Turn it in for 10 additional points on your test.
I will give students a chance to retake the test in class.
Once again, it is due on WEDNESDAY.
