Domains & Kingdoms

2. Kingdom Protista...
First group of organisms to have a nucleus (eukaryotic).
They are not animals, plants,
or fungus

3. Kingdom Protista...
Most are unicellular
Amoeba
Euglena
Paramecium

4. A few are multicellular
Kingdom Protista...
A few are multicellular
Kelp
Brown Algae

5. Kingdom Protista... Protists have no specialized systems.
They do everything within a single cell.
Paramecium eating
Red yeast
Amoeba eating paramecium

6. Types of Protists
Protists are Grouped by how they get energy. They can be
Heterotrophic
Autotrophic
Symbiotic

7. Heterotrophic Protists eat other organisms
Heterotrophic Protists eat other organisms. They are classified by how they move:

8. Flagellates move with a whip-like tail called a flagella.

9. Ciliates move with many cilia or
hairs

11. Dangerous Ameba

13. Amoebas change their shape making cytoplasmic projections called
Pseudopods.
Amoeba –
performing
phagocytosis
(engulfing food)
Similar to our
white blood cells

14. Amoeba phagocytosis

16. Passive protists don’t move at all, they depend on air or water to carry them.

17. A second type of protist are the
Symbiotic protists. They form a
relationship with another organism.

18. Some are mutualistic- both organisms are benefited.
Coral(an animal) and
Zooxanthellae(a protist)
help each other to survive

19. Trichonympha protists live in the intestines of
termites, helping them digest wood.

20. Some protists are parasitic and are responsible for some of the world’s most deadly diseases!
Trypanosoma- causes African Sleeping Sickness

21. Protozoan Diseases Malaria Severe flu-like symptoms to coma and death,
carried by the mosquito

22. Protozoan Diseases Amoebic dysentery
Fever, stomach cramping. Dehydration
Water-borne pathogens
Giardia
Cryptosporidium

23. Naegleria fowleri, the brain-eating amoeba that causes primary amebic meningoencephalitis

24. Autotrophic Protists
Unicellular algae and multicellular algae Get their energy by photosynthesis Produce half of the world’s oxygen

25. They are the base of most aquatic food chains
Ecological Roles- photosynthetic protists play an important role on earth
They are the base of most aquatic food chains

26. Provide energy for coral
Some protists live
inside coral and
provide food for
it’s survival

27. Giant Kelp Forests

28. Provide shelter
Autotrophic protists help
recycle sewage

29. Red Tide Algal Bloom- protist grow to enormous
numbers and then disrupt the normal
ecosystem—reduce amount of oxygen
