Abstract
The intergrated perfusion/charge-pulse technique allows the separated determination of the electrical properties of the tonoplast and the plasmalemma of giant-celled marine algae with exact manipulation of the vacuolar and external solution. The hydrostatic pressure in the cells (the so-called turgor-pressure), which is one of the most important parameters for the physiology of the cell, can easily be regulated during the experiments. The charge-pulse relaxation spectrum of Valonia utricularis and Ventricaria ventricosa showed a biphasic shape that could be described by the sum of two exponentials decays. The time constants of the two relaxations were calculated...
