Using ion-selective micro-electrodes electrical signals in plants moving from leaf to leaf could be measured. The speed of the signals spreading as voltage changes over cell membranes ranged from 5 to 10 cm per minute. The scientists discovered this new kind of electrical signal transmission system by applying a novel method: Filamentary electrodes were inserted through open stomata directly into the inner leaf tissue and then placed onto the cell walls (see picture). Stomata are...
