1. Identify the different types of protists.

2. Fill out the table to compare the characteristics of different types of protists

3. Recognize the importance of protists on Earth.

4. Say something about these plant-like protists.

5. If there are plant-like protists, do you think there are also animal-like?

6. What do you think this organism is—plant, animal, or fungus?

7. Have you ever seen bread turn moldy or a log covered in slimy yellow patches?

8. Those slimy growths are similar to fungus-like protists. They play an important role in nature by breaking down dead material—like nature’s recyclers!

9. Fungus-like Protists What are

10. Fungus- like Protists that look like fungi but are not true fungi.

11. Fungus- like They are heterotrophs (cannot make their own food).

12. Fungus- like They are decomposers: they feed on decaying matter.

13. Fungus-like Protists Types of

14. SLIME MOLDS Live in moist, shady places. Can move like amoebas when food is scarce. Example: Physarum

15. WATER MOLDS (OOMYCETES) Live in water or damp places. Some are plant parasites (cause diseases in crops like potatoes).

16. WATER MOLDS (OOMYCETES) Example: Phytophthora infestans (caused the Irish Potato Famine).

17. CHARACTERISTICS Like fungi: absorb nutrients from environment.

18. CHARACTERISTICS Unlike fungi: their cell walls contain cellulose (not chitin).

19. CHARACTERISTICS Often live in damp soil, rotting material, or water.

20. Summary

21. Fungus-like protists are not true fungi, but they act as decomposers. Slime molds move and feed like amoebas.

22. Water molds live in moist environments and can cause plant diseases. They are important in ecosystems because they recycle nutrients from dead organisms.
