Chapter 9: Paramecium multimicronucleatum - Video Of The Contractile Vacuole Complex


Video 2: In vitro CVC rounding/relaxing cycles

An in vitro CV in a ruptured Paramecium cell is surrounded by cytoplasmic vesicles and partially diluted cytoplasmic fluid. The CV periodically rounds and relaxes. One radial arm is visible which can swell as it is still able to accumulate fluid and it then fuses with the CV as the CV relaxes. Several frames were published in Tani, Allen and Naitoh, J. Exp. Biol. 203:239-251, 2000.
