1. PROTISTS

2. PROTISTS COMMON EXAMPLES: EUKARYOTIC VERY DIVERSE GROUP
Amoeba, paramecium, euglena, volvox, plasmodium
EUKARYOTIC
Have a nuclear membrane
VERY DIVERSE GROUP
most are unicellular, microscopic, aerobic
Some are autotrophic, heterotrophic, sexual, asexual

3. PROTISTS DOMAIN EUKARYOTA KINGDOM PROTISTA
Any eukaryote that is not classified as a fungus, plant, or animal is a PROTIST

4. PROTISTS ANIMAL-LIKE PROTISTS = PROTOZOA PLANT-LIKE PROTISTS = ALGAE
Classified by method of movement
PLANT-LIKE PROTISTS = ALGAE
Classified by pigment color
FUNGUS-LIKE PROTISTS = MOLDS
Classified by body form

5. PROTISTS
PROTOZOA
Heterotrophic
Unicellular
4 groups

6. PROTISTS SARCODINA Aquatic
Move by extending lobes of their cytoplasm called pseudopods (false feet)
Example: Amoeba proteus

7. PROTIST

8. PROTISTS CILIOPHORA Cilia for locomotion Larger than other protists
Example: Paramecium

9. PROTIST

10. PROTISTS SPOROZOA Members cannot move All are endoparasites
Example: Plasmodium – causes malaria

11. PROTISTS

12. PROTISTS PLANT-LIKE PROTISTS Most perform photosynthesis
Contain chlorophyll in chloroplast and usually other pigments
Divided into groups by pigment color
Euglenophyta
Green algae
Red/brown/gold algae
Dinoflagellages (clear)

13. PROTIST EUGLENOPHYTA Stigma (eyespot) - light sensitive
Movement toward light using flagella; flagella pulls cell
Example: Euglena; Volvox

14. PROTISTS

15. PROTISTS
GREEN ALGAE
Contain chlorophyll b is their main type (which is very similar to land plants)
Many live in symbiotic relationships
Lichen – organism composed of an algae and a fungi living together as one
Example: Spirogyra

16. PROTISTS

17. PROTISTS

18. PROTISTS

19. PROTISTS Red/brown/gold algae
Brown algae used as a thickening agent in toothpaste, pudding, ice cream; ex. Giant kelp

22. PROTISTS
Gold algae is especially important in lakes, not true autotrophs because nearly all become heterotrophic in the absence of adequate light; ex. Diatoms

23. PROTISTS Dinoflagellates
When agitated, undergo reaction that produces light  bioluminescent
Cause red tide

24. PROTISTS

25. PROTISTS FUNGUS-LIKE PROTISTS (MOLDS)
Called “molds” because they are decomposers

26. PROTISTS IMPORTANCE OF PROTISTS ECOLOGICAL ROLES
Provide an essential food base in aquatic food chains
Carry out more than 30-40% of Earth’s photosynthesis
Protozoans help keep the number of bacteria in check

27. Give Me A Hand Assignment
Trace your non-writing hand in the middle of the paper
Write “Protists” in the palm
Use your notes to find examples to put on each finger and one non-example for the thumb. Each example needs a picture! USE AT LEAST 4 COLORS!!
Wrtite a 4-6 sentence paragraph explaining how your examples relate to the topic.
