The flashcards below were created by user Will123 on FreezingBlue Flashcards. What would you like to do?


  1. What is the reynolds number a ratio of?
    Reynolds number Re is a ratio of the inertial forces to viscous forces
  2. Whats Re equal to
    Re= pVL/micro
  3. What are three different types of pseudopodia?
    • Lobopodia
    • Axopodia
    • Filopodia
  4. What do lobopodia look like?
    A whole bunch of blunt finger looking things used in motion
  5. What are Axopodia like
    .fingerlike; filopodia are slender and tapering, occasionally forming simple, branched networks; reticulopodia, found in the foraminiferans, are branching filaments that fuse to form food traps;and axopodia, characteristic of the actinopods, are long and sticky (like reticulopodia) but radiate singly and have a stiff, internal rod composed of numerous microtubules
  6. What do naked amoebas use lobopodia for?
    For motion and forming food vaculous
  7. What relationship cna protozoans have to metazoans
    • Benificial
    • Harmful
    • Harmless
  8. What is mutualism commensalism and parasitism
    Mutualism - Each symbionit will derive a benifit from the relationship.
  9. What is commensalism
    Commensalism one organism benifits while the other is unaffected
  10. What are two mdoels of locomotion in amoebid?
    • 1. Polymerization of actin
    • 2. depolymerization of actin
  11. Waht is one functional use of protozoans and metazoans (think: guy intetstines)
    Metazoans generally are not able to breakdown cellulose. so Trichomonas lives inside the guts of termites to do it for them.
  12. What do you think of when you hear the species Trichomonas
    Trichomonas - resides within termite gut to help breakdown cellulose
  13. Do humans have any of these trichomonas? If so where do they reside?
    Yes humans have trichomonas.Trichomonas reside within the mouth of humans
  14. What do these protozoans inside the human generally feed on?
    Bacteria
  15. What parasite causes sleeping sickness?
    Trypanosome brucei
  16. What is Trypanosomas Vector?
    Tsetse fly
  17. How many steps are there to the Trypanosoma Sleeping sickness
    there are 8 Steps in total
  18. What is the first step in Trypanosmas rampage
    • 1.Tstse Fly takes a blood meal

    • 6.
    • 7.
    • 8.
  19. What is the second step in Trypanosoma
    • 1. Tstse Fly takes a blood meal
    • 2. Trypanosomas are now in the blood which carries them to other sites
    • 3.
    • 4.
    • 5.

    • 4.
    • 5.
    • 6.
    • 7.
    • 8.
  21. What is the fourth step in Trypansoma
    • 1. Tstse Fly takes a blood meal

    • 3. Trypanosoma multiply by binary fission in body fluids
    • 4. Trympanosomas remain in blood
    • 5.
    • 6.
    • 7.
    • 8.
  22. What is teh fifth step in Trypanosoma
    • 1. Tstse Fly takes a blood meal
    • 2. Trypanosomas are now in the blood which carries them to other sites
    • 3. Trypanosoma multiply by binary fission in body fluids
    • 4. Trympanosomas remain in blood
    • 5. Tsetse fly again takes a blood meal ingesting trympanosoma
    • 6.
    • 7.
    • 8.
  23. What is the sixth step in Trympanosoma
    • 1. Tstse Fly takes a blood meal
    • 2. Trypanosomas are now in the blood which carries them to other sites
    • 3. Trypanosoma multiply by binary fission in body fluids
    • 4. Trympanosomas remain in blood
    • 5. Tsetse fly again takes a blood meal ingesting trympanosoma

    When they reside within the human hosts lymph and spinal fluids. not a good thing id imagine
  27. OMFG check out lecture 5 the last slide good luck
