1. Warm Up 2/10/16 What Domain is Protista in?
What are the 3 types of nutrition fungi utilize?
Give on example of mutualistic fungi.

3. Protista General Characteristics
Protista: similar to animals, plants, and fungi BUT do not possess all the characteristics of those kingdoms
Protista General Characteristics
All are eukaryotic
Usually found in damp environments

4. Classifying Protists
Classified based on method of obtaining nutrition & movement
3 groups of protists
Animal Like: Captures and ingests food (heterotroph).
Plant Like: Photosynthetic (autotroph). Can be multicellular or unicellular.
Fungus like: absorb nutrients (heterotroph).

5. Origin of Kingdom Protista
Endosymbiotic Theory: eukaryotes formed when a large prokaryote engulfed a small prokaryote, which evolved into a more complex organism
Scientists think that protists might have been the 1st eukaryotes to appear

6. II. Protozoans (Animal like protist)
Ciliates: have short hair like projections for movement or used to move food particles into the oral groove
- found in most aquatic environments
Ex: Paramecium
Contractile Vacuole
Oral Groove
Cilia
Vacuole
(food and waste storage)

7. b. Sarcodines Ex: Amoeba
Use Pseudopods (“false foot” or extension of the cytoplasm) is used for locomotion and feeding. Feeds by surrounding and enveloping smaller organisms
Ex: Amoeba
Pseudopod

8. c. Sporozoans Sessile (no movement) and parasitic.
Reproduce using spores
Ex: Plasmodium  Causes Malaria

9. d. Zooflagellates use flagella for movement
Some are free living, many are parasites
Ex: Trypanysoma brucei  causes
African Sleeping Sickness

10. III. Plant Like Protists a. General Characteristics
All are photosynthetic.
Not considered plants because they do not have roots or leaves
Unicellular or multicellular
Categorized on type of pigment, food storage method & cell wall composition

11. b. Dinoflagellates Unicellular.
Autotrophs, but can be heterotrophs when there is no sunlight.
Importance: cause algal blooms, which depletes nutrients killing marine life
Ex: Red Tide

12. c. Euglenoids Unicellular. Autotrophs or heterotrophs if needed.
No cell wall, but has a pellicle.

13. d. Algae largest protists Photosynthetic Uses: food source
Ex: Brown Algae, Green Algae, Red Algae

14. Unicellular Green Algae
Volvox: forms colonies
Spirogyra

15. IV. Fungus Like Protists
Different from fungi because have a different cell wall & contain centrioles (which fungi do not have)
Examples: Slime Molds, Water Molds & Downey Mildew
