  1. _?_ are singled-celled eukaryotes; few (including seaweeds) are multicellular, but simplistic in tissue organization.
    Protists
  2. What are protozoans?
    Animal-like organisms that require oxygen (most do), don't perform photosynthesis and are motile.
  3. What are algae?
    Plant-like organisms; can perform photosynthesis.
  4. What makes green algae green and what organelle is involved?
    Since green algae are plant-like organisms, they contain an organelle that all plants have and that is called chloroplast. Through photosynthesis, a green pigmentation is produced thanks to chlorophyll.
  5. Are there types of algae besides green algae? If so what are they and can you give an example of each?
    • Golden brown algae (Fucus)
    • Red algae (Pfiesteria)
  6. Are there harmful algae? If so can you give an example?
    • Dinoflagellates in the genus Alexandrium responsible for "red tide" and paralytic shellfish poisoning
    • Pfiesteria: mysterious Chesapeake Bay algae
  7. Protozoans are characterized based on their mode of  _?_.
    Locomotion
  8. Some protozoans make _?_ allowing them to survive adverse conditions.
    Cysts
  9. What are the three categories of movement in protozoans?
    • Ciliates
    • Flagellates
    • Amoeboids
  10. A paramecium is an example of a _?_ protozoan.
    Ciliated
  11. Euglena is an example of a _?_ protozoan.
    Flagellated
  12. Some flagellates can lead to disease can you give some examples?
    • Trypanosoma
    • Giardia
    • Trichomonas
  13. The disease that can be transmitted by drinking fresh water that hasn't been filtered and is carried by some animals such as beavers is called _?_.
    Giardiasis
  14. The sexually transmitted disease that can be passed on to women by infected men is called _?_.
    Trichomonas vaginalis
  15. The disease that causes the host to sleep more during the day and become agitated at night and is transmitted by the tsetse fly is called _?_.
    Trypanosoma gambiense (African sleeping sickness)
  16. The genus name of Chagas disease is _?_ and this is transmitted by the "kissing bug" (bites face at night).
    Trypanosoma cruzi
  17. An amoeba is an example of a _?_ protozoan.
    Amoeboid
  18. A disease that causes very, very serious dysentery (diarrhea), is caused by being infected by contaminated waters, and mostly kills young children and babies is called _?_.
    Entamoeba histolytica
  19. Some apicomplexan can lead to disease can you give some examples?
    • Plasmodium
    • Toxoplasma
    • Cryptosporidium
  20. The disease that causes Malaria and MRSA and is spread by mosquitoes is called _?_.
    Plasmodium vivax
  21. The disease that is spread through cat feces that leads to having flu-like symptoms is called _?_.
    Toxoplasma gondii
  22. The protozoan that causes cysts, is spread by animals waste, can get into drinking water contaminated with sewage and is chlorine resistant is called _?_.
