CONDUCTIVITY AND PERMEABILITY [PDF]
Journal of General Physiology, 1921 An electrical current passing through a living plant flows partly through the cell wall and partly through the protoplasm. The relative amounts of these two portions of the current can be calculated. The outcome of such calculations shows that the conclusions drawn from the study of the resistance of the tissue as a whole apply also to ...
