Abstract:
It is well known that specialized gravireceptory cells have been formed in the course of evolution in the majority of multicellular organisms. These are statosytes (statenchyme cells) in higher plants and otolith apparatus cells in animals. The mechanisms of gravity reception and the generation of gravitational stimuli in these cells are well understood. Therefore, our attention was focused on cells devoid of special gravireceptory mechanisms, namely cell cultures grown in vitro (fibroblasts and osteoblasts) and unicellular free-swimming (i.e. possessing a locomotor apparatus) organisms. These were mainly representatives of two classes: Ciliata and Flagellata. The choice of the objects of study was mainly determined by their ecological and physiological characteristics with the main goals of this work.
