## Summary The action potential (AP) in __Chara__ is associated with a transient elevation in the concentration of cytoplasmic‐free Ca^2+^ ([Ca^2+^]~cyt~). The quenching properties of the fluorescent Ca^2+^ indicator dye fura‐dextran, in combination with Mn^2+^, was used to investigate whether this
