Abstract:
A mathematical model of push-pull movement of linear protoplasm is proposed. The model is considered for a two-chamber system whose autooscillations are induced by an active force during contractions of the filaments. Estimations of the rate of protoplasm flowing, the time of quenching in the passive system, as well as the general course of time relationships of the rate and radial changes of the strand radius agree with the experimental data.
