1. Protist General Biology Mr. Cobb

2. General Characteristics  Eukaryotic  Microscopic  General “catchall” kingdom  Like the “junk” draw in the kitchen  Described as:  Animal-like  Plant-like  Fungus-like

3. 3 Types of Protists  Protozoan – animal-like  Algae – Plant-like  Fungus - like

4. Protozoan characteristics  Microscopic and unicellular  Most are aquatic  Classified by locomotion (movement)

5. Sarcodina Phylum Amoeba: no body shape Move slowly with a pseudopodium Responds to stimuli Surrounds its food and engulfs it

6. Amoeba

7. Cilates  Paramecium:  Move by cilia  Covered with cilia (little hairs for movement)  Oral groove to take in food

8. Nassula Freshwater Ciliate

9. Freshwater Ciliate

13. Sporozoans  Do not move  Parasitic  Plasmodium – causes malaria in the Anopheles mosquito Ruptured Red blood cells Life cycle Anopheles Mosquito

14. Flagellates  Propel by one or more flagella  Known as Zooflagellates  Causing African Sleeping Sickness Tsetse Fly Trypansome

15. Algae  Unicellular or colonial  Found in all water  Primary food source for zooplankton  70% of photosynthesis on the planet

16. Algae Types  Euglena (algae with flagella)  Green Algae (stuff on the boat and pool)  Golden Algae  Diatoms (contain silica) (geometric shapes)  Brown Algae  Red Algae  Dinoflagelletes ( contain 2 flagellas and cause red tides)

24. Dinoflagelletes causing red tides

25. Fungus-like Protist  Hetertrophic like Fungus but:  Cellulose cell wall  Motile  Two types:  Watermolds  Slimemolds

26. Watermolds  The “stuff” growing on dead fish.  Caused Potato blight

27. Slimemolds
