Abstract
Using the liquid microelectrode technique, the electrical potentials of nodal cells and the with them internodal cells neighbouring, of Nitellopsis obtusa plants of the Characeae family were determined. A specific variation in the potential of nodal cells in the form of cacophony-type irregular disturbances was also found, indicating that the node is not a passive mechanical element controlled by internodal cells, but is a complex system of coupled-, and different metabolic oscillators.
