Solute transport at the cellular level
- 60 Downloads
The driving forces for solute transport at the membrane level in plants are the same as those in other biological membrane systems. However, the presence of a cell wall and of a vacuole in plant cells are features which add considerably to the technical problems of measuring the various parameters. The basic transport equations (see below) may be applied to transport across plant cell membranes, but the application of such an approach to the cells and tissues of higher plants is severely limited. Often the cells are too small to allow any accurate electrophysiological measurements to be made and much of the basic investigation has so far been made on the transport properties of large algal coenocytes (see Section 2.2).
