2. They are projections of the cytoplasm used for feeding and movement.
What are pseudopods? How do protists use them?
They are projections of the cytoplasm used for feeding and movement.
Back

3. Complete the chart
Back

4. Label the paramecium
Back

5. Draw 3 protists that move in 3 different ways.
Back

6. Which diagram looks like the movement of cilia and which looks like the movement of flagellum
Like flagellum Euglena
Like cilia (Paramecium)
Back

7. How do amoeba reproduce?
Asexually by mitosis
Back

8. What is conjugation? Back
A process that allows protists to exchange genetic materials with other individual
Back

9. Within a large population how does conjugation benefits protists?
By creating and maintaining genetic variation or diversity.
Back

10. What occurs in the process of alternation of generation?
It is a means of sexual reproduction in which the life cycle switches between haploid and diploid stages,
Back

11. Back Conjugation begins when 2 paramecia attach to each other
Meiosis produces 4 haploid micronuclei
In each cell, 3 of the micronuclei disintegrate
The remaining micronucleus in each cell divides by mitosis
The 2 cells exchange one haploid micronucleus
In each cell the micronuclei fuse to form a single diploid micronucleus and the macronucleus disintegrates
Each cell forms a new macronucleus from its micronucleus
Back

12. How do autotrophic protists make the diversity possible ?
They are the base of food chain
Back

13. What are phytoplankton?
Small photosynthetic organisms found near the surface of the ocean, many are autotrophic protists
Back

14. How do protists help maintain equilibrium in coral reef ecosystem
Red algae support coral reefs by providing much needed nutrients for coral animals, red algae also produces minerals corals need to form reefs
Back

15. How can algal bloom be harmful?
Daily Double
A bloom can quickly deplete the water of the nutrients, the decomposition of the dead algae can robe the water of its oxygen, choking resent fish and invertebrates life.
Back

16. What is the function of food vacuole?
It temporary stores food until it can be digested
Back

17. What are cilia? How are they used by protists?
They are short hair like projections used for movement
Back

18. What are slime molds? Back
They are heterotrophic protists that thrive on decaying organic matter
Back

19. Spores are made by meiosis inside the sporangium.
By what process are haploid spores made by a water mold? Where does the process occures?
Spores are made by meiosis inside the sporangium.
Back

20. What structure does the plasmodium eventually develop into
What structure does the plasmodium eventually develop into? And what is the function of that structure?
Daily Double!
Develops into sporangia which produce haploid cells
Back

21. Who am I? I am a locomotion organ found in some protists (I also help in feeding) yet they call me a liar
Pseudopodia
Back

22. In amoeba indigestible materials are kept in contractile vacuole
Food
Back

23. A gullet is an organ used by paramecium for reproduction
Feeding
Back

24. In a slime mold’s life cycle germinating spores release amoeba like cells
True
Back

25. Water mold grow on dead or decaying plants and animals
True
Back

26. Some protists have about three or four thousands of flagella
One or two
Back

27. How does the protist Trichonympha make it possible for termites to eat wood?
By manufacturing the enzyme cellulase which breaks the chemical bonds of cellulose.
Back

28. What causes malaria?
Plasmodium
Back

29. How do amoebas capture and ingest food?
They use their pseudopods to surround the food particle or cell and take it inside themselves ingesting it.
Back

30. If 2 organisms are making benit of each other this symbiotic relation is called what? Mention an example
Mutualism – The example is termites and trichnympha
Back

31. Parasitism, malaria Back
If an organism is making benefit while hearting another one this relation is called what – mention an example
Parasitism, malaria
Back
