A small number of the mutants in this class produced sperm that appeared immotile; most produced reasonable quantities of motile sperm.
Many of these immotile spermatids are dislodged from the spermatheca and swept away as oocytes parade through the reproductive tract.
Due to the flagellation constraint, the cost of reproduction (in terms of the amount of time spent in an immotile stage) increases with increasing colony size.
He showed that the amoeba Pelomyxa became immotile upon illumination, whereas the photosynthetic alga Euglena was attracted to light.
The immotile cilia lack the motor protein dynein, which is essential for their movement.
