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.
