Abstract

A model for overcoming the gravity by moss sperm cells is proposed here. It is based on the assuming that the tip of constantly coiled sperm cell slips on surface of moss tissue, to which the cell is pressed by tensile strength of water. This tip and the cell mass center don’t coincide. Therefore, there appears a torque expressing gravitaxis of physical nature. In puddles the cells can successfully overcome the gravity detecting thermal fluctuations of their velocities, which expresses gravikinesis of physical nature. It can considerably improve fertilization of mosses.
