WebbTurgor Pressure Turgor pressure keeps plant cell vacuoles full and pressing against the cell wall. Some plants, as a result from touch the water flows out of the vacuole, and the cell collapses. This is a physiological adaptation, leading to a behavioural adaptation. The mimosa pudica responds to stimulus of touch. WebbThe physical behaviour of gases is explained by the kinetic molecular theory of gases. The number of collisions that gas particles make with the walls of their container and the force at which they collide determine the magnitude of the gas pressure. Temperature is proportional to average kinetic energy.
