Plant Physiology 45:126-132 (1970) © 1970 American Society of Plant Biologists Diffusion and Osmotic Transfer in Corn Mitochondria 1a Department of Agronomy, University of Illinois, Urbana, Illinois 61801
An equation based on the assumption of solute diffusion into an expanding sink is derived and describes the passive swelling of corn shoot (Zea mays L.) mitochondria. The experimental data show that corn mitochondria not only swell due to diffusive forces but also contract according to osmotic phenomena, provided sufficient impermeant solute is included to prevent lysis.
