1. Introduction and the Animal-like Protists
Jason Burton

2. Describe a Protist? Eukaryotic or Prokaryotic?
Multicellular or unicellular
Both
Autotroph or Heterotroph
Cell wall or no cell wall

3. Why are there so many different characteristics?
Because there are so many different types of Protists.
And they are divided into three categories.
And their range in size can be from microscopic to a 35 meter (about105 feet) tall kelp.

4. Why and how are they divided into three categories?
Classification – to make them easier to study.
How?
They are classified into their categories primarily by the way they obtain food.

5. What are the three categories?
First Category
Animal-like Protists
How do they obtain food, Autotrophs or Heterotrophs?
Right!!! Heterotrophs

6. What are the three categories?
Second Category
Plant-like Protists
How do the obtain food, Autotrophs or Heterotrophs?
Right!!! Autotrophs

7. What are the three categories?
Third Category
Fungus-like Protist
How do the obtain food, Autotrophs or Heterotrophs?
Right!!! Decomposers (heterotrophs)

8. Let’s look at each group more closely.

9. Animal-like Protists Also call Protozoans Proto means? zo means?
First
zo means?
Animal
First Animal!!!
Paramecium

10. Animal-like Protists How many groups of animal-like Protist are there?
There are four groups of animal-like protist.
Specifically four phyla (plural for phylum)
The animal-like protists are place into one of the four phyla base on how they ___________.
Move!!
Animal-like Protist are unicellular

11. Animal-like Protists Phyla One: Zooflagellates
Phylum: Zoomastigina
Movement: Flagella (plural) or Flagellum (singular)
Can have one, two or many flagella!!
Lives in fresh water lakes, streams, the ocean or host organisms.
Heterotrophic by absorbing decomposing matter or living inside a host.
Reproduction
Asexually
Binary Fission
Sexually
Meiosis
Sex Cells
Examples:
Leucocryptos marina

12. Animal-like Protists Phyla Two: Sarcodines
Phylum: Sarcodina
Movement: pseudopods
projection of cytoplasm, or false foot, used by some protists for feeding or movement
Lives Everywhere: freshwater, marine (salt water) and host organisms.
Captures food with pseudopod and digests in with a food vacuole.
Reproduction
Binary Fission
Examples: Amoeba, Foraminiferans , Heliozoans

13. Animal-like Protists Phyla Two: Sarcodines
Amoeba

14. Animal-like Protists Phyla Two: Sarcodines
Amoebas

15. Animal-like Protists Phyla Two: Sarcodines

16. Animal-like Protists Phyla Two: Sarcodines

17. Animal-like Protists Phyla Two: Sarcodines
Foraminiferans

18. Animal-like Protists Phyla Two: Sarcodines
Heliozoans

19. Animal-like Protists Phyla Three: Ciliates
Phylum: Ciliophora
Movement: Cilia
short hair-like projection similar to a flagellum; produces movement in many cells
Lives in freshwater and marine environments, free-living
Captures food with help of cilia and digests in with a food vacuole.
Reproduction
Conjugation
Examples: Paramecium, Coleps, Stentor, Vorticella, Carchesium colony

20. Animal-like Protists Phyla Three: Ciliates

21. Animal-like Protists Phyla Three: Ciliates
Paramecium

22. Animal-like Protists Phyla Three: Ciliates

23. Animal-like Protists Phyla Three: Ciliates

24. Animal-like Protists Phyla Three: Ciliates

25. Animal-like Protists Phyla Three: Ciliates

26. Animal-like Protists Phyla Four: Sporozoans
Phylum: Sporozoa
Movement: None (parasitic)
Sporozoans are parasites of a wide variety of organisms, including worms, fish, birds, and humans.
Reproduction
sporozoites.

27. Animal-like Protists Phyla Four: Sporozoans

28. Animal-like Protist and Disease
What Diseases do animal-like protist cause?
Malaria
Sporozoan: Plasmodium
African sleeping sickness
Zooflagellates: Trypanosoma
Amebic dysentery
Sarcodina: Entamoeba (amoeba)
Zooflagellates: Giardia
Trypanosoma

29. Ecology and Animal-like Protists
How are they important to the environment?
Recycling nutrients by breaking down dead and decaying matter.
Symbiotic Relationships
Trichonympha is a zooflagellate
that lives in
the gut of termites.
- Breaks down wood for the
termites.
