Plant cell growth from first principles: How physical theory can broaden our understanding of plant cell volume growth.
Traditionally, the theoretical background for problems of plant growth are developed "a posteriori" from observations of experimental outcomes and common sense. This is in general necessitated by the complexity of biological systems and by the inadequacy of mathematical and/or physical knowledge. It is possible however, that in the case of plant cell volume growth there is sufficient basis in physical first principle to permit a reasonably complete mathematical model to be constructed "a priori". We believe that in the case of cylindrical plant cells, it is possible to construct a physical model of plant cell wall stress relaxation which in entirely based in physical first principles and has no empirically derived component. The advantages of such a model lie first in the universality of its predictions, and second in the lack of any arbitrary constants or "Fudge factors".
