SUMMARY It is proposed that long distance transport of solutes is controlled by regulation of turgor. Turgor constancy is maintained by import or export of solutes and water from or to the apoplast. This will cause changes in the apoplast pressure which will unbalance waterpotential equilibrium between the apoplast and other cells. Turgor changes are thus caused in these cells which will consequently import or export solutes and water to readjust their turgor.
