BISC 121Lg Lecture Notes - Lecture 10: African Trypanosomiasis, Kinetoplast, Alveolate
Document Summary
Lecture 10: multiple flagella, 2 separate nuclei a simple cyotoskeleton no mitochondria or plastids, giardia lambia is an example of it. Trichomonas vaginalis is a harmful parabasalid: causes trichomoniasis, women develop symptoms but (cid:373)e(cid:374) do(cid:374)"t, sti spread through skin to skin contact. Mixotrophs can have a preference for heterotrophy (eating) over autotrophy (photosynthesis) or vice versa. Kinetoplastids have a single large mitochondrion associated with a unique organelle, the kinetoplast: the kinetoplast houses extracellular dna, symbiotic and include pathogenic parasites, ex) african sleeping sickness. Alveolata are unicellular protists with alveoli: alveoli- subcellular cavities, dinoflagellates include abundant components of phytoplankton. 2 flagella sit in perpendicular grooves and they spin. Have blooms (sudden increases in the population of the organism) that cause red tides toxins produced by some red tide organisms can kill many invertebrates and fish: can be harmful to humans. Alexandrium causes paralytic shellfish poisoning which is often fatal.
