1. Kingdom Protista

2. What are protist? What are the classifications of Protist?
Eukaryotes, Mostly Unicellular Organism
Evolved from the symbiosis of several cells of Archaebacteria
Endosymbiotic Theory
Lynn Margulis
What are the classifications of Protist?
Heterotrophs
Animal – like Protozoa (classified by locomotion)
Fungus – like Protist (absorb nutrients from dead/decaying organisms)
Autotrophs
Plant – like Protist (unicellular and plant like protist)

3. Animal Like Protist

4. Protist Phylums Phylum Sarcodina
Free living- Fresh or brackish water, bottom dwellers
Parasitic
Pseudopod: temporary cytoplasmic projection
Food vacuoles, some have shells
Use pseudopods to take in food by phagocytosis
Use psedopods for movement and feeding (phagocytosis)
Example: Amoebas, Foraminiferan, Heliozoan

5. Parts of the amoeba

6. Protist Phylums Phylum Ciliophora (Ciliates)
Free living- Fresh and salt water
Have two nuclei: Micronucleus and Macronucleus
Contractile vacuoles, gullet, cilia
Use cilia to sweep food particles into the gullet
Use cilia for movement (short hair like-projections)
Example: Paramecium

8. Protist Phylums Phylum Zoomastiginia Free living – lakes or streams
Symbiotic relationship with host
One or 2 flagella to swim
Feed by absorbing nutrient
Example: Trypanosoma
Causes sleeping sickness spread by tsetse fly
Giardia

10. Protist Phylums Phylum Sporozoa Habitat – host organism Sporozoites
Live off the host. Infects and destroys RBC
No locomotion
All parasites with complex life cycles
Example: Plasmodium (causes malaria)
