Protista Review

Animal-like1. Protista is from the Greek word that means First2. What are 3 methods of motility in protists? Pseudopods, Cilia and Flagella3. What is the endosymbiont hypothesis? A theory stating that eukaryotes evolved through a process where different types of free living prokaryotes became incorporated inside lager prokaryotic cell and eventually developed into mitochondria, chloroplasts, and possibly other organelles4. What is the name for animal-like protists? Protozoans5. What does ciliophora use for movement? Short hair like projections6. What is an example of a ciliate? Paramecium7. What are trichocycts? A small sac in certain protozoans that contains a hair like stinger.8. What is a gullet? Water/food is swept into, forced into cavities called food vacuoles9. What do zoomastigina use for movement? Flagella, long, whip like projections10. What are two examples of zooflagellates? 1) Trypanosome-causes sleeping sickness and 2) trichonympha 11. What do sporozoa use for movement? Spores12. What is an example of sporozoa? Malaria13. What protist produces African Sleeping Sickness? Trypanosome14. What protist produces malaria? Sporozoa15. What protist is found in the digestive systems of termites? Trchonympha16. How do sarcodines move? pseudopods17. What is an example of a sarcodine? Amoebas18. How do amoebas capture and digest food? Phagocytosis ( Captures and eats particles and other cells)

19. Label the paramecium:

Plant-like1. What are accessory pigments? Absorbs light at different wave lengths than chlorophyll, passes the energy they absorb to the algae’s photosynthesis.2. What does euglena have that help it find the brightest areas? Red eye spot3. What is a pellicle? It is the tough intricate membrane of a Euglena4. What type of protists are luminescent and produce red tides? Dinoflagellates (Pyrrophyta)5. Explain what each structure does in algae: holdfasts- anchoring devices, stipes- Flexible stems, blades- Maximize their exposure to light, bladder- Store gases for buoyancy.6. What group of plant-like protists do dinoflagellates belong to? Pyrrophyta7. What group of plant-like protists do green algae belong to? Chlorophyta (Chlamydomes, Volvox, Spirogyra, Ulva)8. What group of plant-like protists do brown algae belong to? Phaeophyta9. What group of plant-like protists do golden-brown belong to? Chrysophyta10. What group of plant-like protists do red algae belong to? Rhodophyta11. What are 4 types of green-algae? Chamydomanes, Volox, Spirogyra and Ulva12.What type of algae includes seaweeds and kelps? Brown algae (Phaeophyta)13. What is alternation of generations? When algae switches back and forth between haploid and diploid. What type of algae can do this? Green Algae (Chlorophyta)14. What type of algae produces algin? Brown Algae (Phaeophyta)15. What type of algae can live in deep water because of their phycobilin pigment? Red Algae (Rhodophyta)16. What colour of light does phycobilin absorb? Blue17. What type of protists have silica in their cell walls? Golden Brown (Chrysophyta)

18. What type of algae contain pectin in their cell walls and store food in the form of oil? Golden Algae (Chrysophyta)

19. Label the picture of Euglena

20. The freshwater algae spirogyra forms long threadlike colonies called Filamentous

Fungus-like1. What type of slime molds do acrasiomycota include? Cellular2. What type of slime molds do myxomycota include? Acellular3. What type of slime molds do oomycota include? Water mold or egg fungi4. What is plasmodia in myxomycota? Protist ( that does not cause malaria)5. What protist is responsible for the great potato famine? Phytophtora Infestans (water mold) What group of protists does it belong to? Oomycota6. What is the largest known alga? Kelp7. What do acrasiomycota do when food supply is down? They gather together to produce a large mass of cells that begin to function as one organism.8. What is a fruiting body? Fruiting body produce haploid spores by meiosis which land in a suitable environment, where they germinate into flagellated gametes. 9. What do myxomycota do when food supply is poor? Fruiting bodies (Sporangia) spring up from the plasmodium.10. What are hyphae? Body forms a mass of thin strands develops into a zoosporangia11. What is zoosporangia? Spore cases, which produces flagellated spores that swim to search for food

12. What are some harmful relationships that protists have with organsims? 13. What are some beneficial relationships that protists have with organisms?
