o Foraminifera= secrete a Calcium Carbonate (CaCO3) shell Pellicle= thin layer of elastic proteins just under the PM protects the cell and allows it to retain a particular shape Anaerobic Flagellates o Diplomonads and parabasalids have multiple flagella & among the few protists adapted to oxygen poor waters Have HYDROGENOSOMES= organelles that produce ATP by an aerobic pathway and release H2 gas as a by product. Evolve from mitochondria and adapt organisms to anaerobic aquatic habitats Thrive deep in seas and lakes & others live in animals Diplomonad Giardia lamblia o Can infect human gut= giardiasis Attaches to intestinal lining and takes up nutrients Excreted in feces if infected Protistan cyst is a dormant cell with a thick protective wall Parabasalid Trichomonas vaginalis o Infects human reproductive tracts and causes trichomoniasis o Doesn’t make cysts o Anti-protozoal drug provides cure Trypanosomes and other Kinetoplastids o Kinetoplastids Flagellated protozoans that have a single large mitochondrion Inside mito., near base of flagellum have clump of DNA

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
