1. Kingdom: Protista

2. A MIXED UP KINGDOM
This kingdom is the most diverse group of organisms.
They move like animals
Photosynthesize like plants
Produce spores like fungus

3. What is a Protist?
Protists live in almost any environment that contains water. Many protists, such as the algae, are photosynthetic and are vital primary producers in ecosystems, particularly in the ocean----plankton.

4. What is a Protist? Eukaryotic Unicellular or multicellular
Heterotroph or autotroph
Some have cell walls

5. Chapter 19, page 502
Pretzel slime mold (pg 502)

6. Move with one or more flagella

7. Pa Paramecium
Euglena

8. Movement & Support Pseudopods Cilia Flagella Some have cell walls
Shells of silica and
calcium carbonate
Some algae have
holdfasts (root) and air bladders (buoyancy)
Pellicle a thin layer supporting the cell membrane

9. Digestion/Obtaining Nutrients
Heterotroph
Endocytosis
Diffusion
Decomposers
Oral groove, cilia, gullet, food vacuoles (pg 507)
Autotrophs with pigments and chloroplasts

10. Nervous/Response Nucleus (macro and micro) Formation of cysts
Eye spot for light detection
Bioluminescent
Produce toxins

11. EUGLENA

12. Circulation
Flow of cytoplasm

13. Gas Exchange
Diffusion

14. Excretion
Diffusion
Contractile vacuole
Anal pore

15. Reproduction Sexual – gametes Asexual – binary fission Conjugation
Spores
Fragmentation
Alternation of generations

16. Helpful Protists Algae (photosynthesis) Diatoms (a group of algae
called phytoplankton.)

17. Harmful Protists Entamoeba histolytica
Giardia lamblia

18. Trichonympha-termites
Trypanosomes-( many species, one causes sleeping sickness carried by tsetse fly)
trypanosome
infecting RBC’s

19. Phytophtora infestans
Gonyaulaux catanella (A marine dinoflagellate protozoan that produces a powerful toxin that accumulates in the tissues of mussels and shellfish; it may cause fatal poisoning in humans who have eaten contaminated shellfish.)
Phytophtora infestans
(caused European potato famine of 1840’s)

20. Malaria
Plasmodium
Infected RBC’s
