Protist Review
1. How do moneran and protist cells differ?
2. Why do protists live in aqueous environments?
3. What three groups make up the kingdom Protista?
4. What characteristics distinguish plantlike protists from animal-like protists?
5. Why are slime molds included in the kingdom Protista
6. Would you expect all students to observe exactly the same shape when observing a live amoeba under the microscope? Explain.
7. Unlike the higher plants, plantlike protists do not have roots, stems, or leaves. Explain why they do not require these structures?
8. What is a pseudopod?
9. Why are multicellular algae not classified as plants?
10. What is the function of the cilia on the surface of Paramecium?
11. What is the function of the micronucleus in Paramecium?
12. a) What is the most common sarcodine example?
b) Its cytoplasm arms are called ___.
c) What general term describes its feeding process?
13. If you observe a contractile vacuole in a protist, what is the most likely habitat for the organism?
14. All protists are eukaryotic. Why, then, is this not considered a trait that defines the group?
15. You have a sample of pond water in which you want to look for protists. The jar has some mud at the bottom and some plant bits as well. Where would you look to find sarcodines? Ciliates?
16. The sexual means of reproduction used by paramecium is _____.
17. What two functions do the cilia provide for the paramecium?
18. Smaller classification groupings for the Animal-like Protists are based
on the following

19. All members of the Kingdom Protista
a) are eukaryotes (b) reproduce sexually (c) have cilia (d) do not have a
membrane around the nucleus
20. The Kingdom Protista is often described as the junk drawer when it comes to classification of organisms. Explain the meaning of this statement.
21. Discuss the importance of the Protists to life in the pond habitat.
22. What are some important differences between Monerans and Protists?
