  • FLAGELLUM/CILIUMA Presentation By: Katie Scheuch

  • FOUND IN THE 3 DOMAINS OF LIFE

    BacteriaArchaeaEukarya

  • FLAGELLUMLong and whip-likeUsed for movementUsually one or very few3 arrangements:Polar flagellationMonopolarBipolarPeritrichous flagellation Moves in a circular screw-like manner

  • CILIUMShort and hair-likeUsed for movement and create current for particle movementMovement is caused by a constant pulsing of the ciliaMany on one cell

  • BASIC STRUCTUREGrows from a basal bodyCylindrical array consisting of:Complete microtubule extending to the tipPartial microtubule that does not go to the tipMotor protein dyneinA single pair microtubules through the center producing a 9+2 arrangementPlasma membraneRadial spokesNexin

  • DISEASESImmotile-cilia syndrome (related to airways)Retinitis pigmentosaMale infertility (inability for the sperm to swim)Decreased female fertility (immotile oviductal cilia)Polycystic kidney disease Developmental defects that cause internal organs to be misplaced or malformed

  • 1) What three ways can flagella form?Monopolar, bipolar, Peritrichous

    2) What structure do flagellum and cilium cells grow from?Basal body
