1. Where do you expect to find a non-flagellated alga? 2. Find Spirogyra. Is it single-celled or multicellular? How does it stay at the surface of the water column? Why would this adaptation be necessary?

The large unicellular organisms have been observed in the vagina smear of a female patient with the symptoms of the inflammatory process of urogenital apparatus. The cell bodies of the organisms were pear-shaped with pointed posterior part, large nucleus and undulating membrane. What protozoans were found in the smear? Select one: a. Trichomonas vaginalis O b. Trypanosoma brucei gambiense O c. Lamblia intestinalis d. Toxoplasma gondii e. Trichomonas hominis

Note its locomotion, termed amoeboid movement, which is the slow extension of the cytoplasm, the associated cytoplasmic streaming, and the apparent retraction   How do you think amoeba eat? What do you think amoeba eat?

Why are red algae red? What distinguishes plasmodial and cellular slime molds? What are the ecological roles of protists? Why are photosynthetic protists so important to marine/aquatic ecosystems? What limits the growth of these organisms and what causes blooms? What will be affected if marine producers are disrupted?

explain How can one distinguish a filamentous fungus from a colorless alga?

Discuss the composition and funtion of the following parts of a flagellete - 1. Flagella 2. Sucking Disc 3. Axostyle 4. Axoneme

Characteristics of Dientamoeba fragilis include all of the following except: a. This organism is a flagellate with internal flagella b. Transmission is thought to occur through the ingestion of specific helminth eggs c. This organism is pathogenic and tends to be more commonly found in children d. Trophozoites contain a single nucleus, while the cysts contain two nuclei

Some literature lists the 4 groups of protozoans as: 1) Flagellates 2) Amoebas 3) Ciliates 4) Sporozoans But other sources list the 4 groups as: 1) Flagellates 2) Amoebas 3) Heliozoans 4) Ciliates Compare and contrast heliozoans vs. sporozoans. Explain why one would replace the other in literature sources.

How does movement of Paramecium compare with that of Amoeba? With a flagellated alga?
