As plant physiology increased steadily in the latter half of the
19th century, problems of absorption and transport of water and of
mineral nutrients and problems of the passage of metabolites from
one cell to another were investigated, especially in Germany.
JUSTUS VON LIEBIG, who was born in Darmstadt in 1803, founded
agricultural chemistry and developed the techniques of mineral
nutrition in agricul ture during the 70 years of his life. The
discovery of plasmolysis by NAGEL! (1851), the investigation of
permeability problems of artificial membranes by TRAUBE (1867) and
the classical work on osmosis by PFEFFER (1877) laid the
foundations for our understanding of soluble substances and osmosis
in cell growth and cell mechanisms. Since living membranes were
responsible for controlling both water movement and the substances
in solution, "permeability" became a major topic for investigation
and speculation. The problems then discussed under that heading
included passive permeation by diffusion, Donnan equilibrium
adjustments, active transport processes and antagonism between
ions. In that era, when organelle isolation by differential
centrifugation was unknown and the electron microscope had not been
invented, the number of cell membranes, their thickness and their
composition, were matters for conjecture. The nature of cell
surface membranes was deduced with remarkable accuracy from the
reactions of cells to substances in solution. In 1895, OVERTON, in
U. S. A. , published the hypothesis that membranes were probably
lipid in nature because of the greater penetration by substances
with higher fat solubility.
