The ion microscope was used to study potassium and calcium distributions in the main motor organ of Mimosa pudica L. The cortex of the motor organ has two cell types differing in location, structure, and ion distribution. Histochemical features portrayed in ion micrographs were plainly correlated with structures seen in the light and electron microscopes.
