Electric spatial patterns are often observed in growth and regeneration Processes in biological systems. Characean algae develop alternating bands composed of acid and alkaline regions along their cell walls, accompanied with the circulating electric current. A theoretical analysis reveals that this state belongs to electric dissipative structures appearing far from equilibrium. A similar banding Pattern can also be found in multicellular systems as bean roots. It is suggested that the current flows to the root tip with the formation of several local current loops in the mature region. These kinds of spatio-temponal electric organization may play an essential role in the growth process.
