Diffusion of Dissolved Substances through Thalli and Leaves of Aquatic Plants

Abstract

So far as I know, there is no information in the literature as to the rate of diffusion of dissolved substances through plant tissues. With animal tissues such investigations have been made, for example, by Krogh¹. Of course, botanists hava been interested in the problem of diffusion, but it has been tackled differently. Instead, investigations have been made as to how the various substances enter the cells. It is the so-called permeability that has been determined. It is, however, impossible to obtain any values for the rate of diffusion through the cells by this method.
