Diffusion and Osmotic Transfer in Corn Mitochondria

摘要

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.
