Among the outstanding unsolved problems of biology is that
of organization of plant tissue, for example, in the growth of a
meristematic mass of cells to a fully differentiated and
functional organ. As the concept of "biological f'ield" seems
to have analogies with that of "electrical field" and moreover
as the latter has obvious possible organizing abilities (transport
of matter electrolytically, etc.) it was felt that an investigation
of the function of the electric fields in living plant material
might give a lead to the broader problem of organization.
While some interesting results on the distribution of
electromotive forces in and near apical meristems vere obtained,
it was thought that the detailed interpretation of these would depend on knowledge of the origin of the biolelectric phenomenon. The research in this way became related to several other general
problems in plant physiology. Certain root potential differences
(p.d.'s) have been f'ound to be connected with tho absorption of
electrolyte by cells and some of the electrical techniques
developed in the laboratory have been applied to the problem
of diffusion of salt across root cytoplasm. The question of the
resistance or the cell surface to diffusion of electrolyte has
been considered in this connection. The research is also related
to the study of the submicroscopic morphology of cytoplasm as
salt uptake is affected by the presence or otherwise of
non-diffuseable ions in the cytoplasm.
