Microelectrode Experiments with Potato Cells: A Reinterpretation of the Experimental Findings

The conclusions of Macklon and Macdonald (1967) concerning theuptake of chloride at low temperatures by potato cells havebeen reinterpreted. It is believed that the lack of agreementbetween their experimental result and what is expected fromconventional electrochemical theory of the passive movementof ions into plant cells is due to the fact that electrodesinserted into potato cells only detect the potential acrossthe plasmalemma.
