Rapid bendings of the pulvinus inMimosa pudica, of the trap lobes inDionaea muscipula andAldrovanda vesiculosa, and of the tentacle in Drosera are triggered by action potentials in their motor cells.
Water extrusion in the trap bladders ofUtricularia vulgaris
From light and electron microscopic observations of the entrance region, it is concluded that the inlet of water outflow is the bifid trichomes which stand on the inner surface of the bladder near the entrance, and the outlet is the outer and middle zones of the pavement epithelium, or threshold, against which the free edge of the door rests.
Water extrustion in the trap bladders ofUtricularia vulgaris
In the capital cells of the pavement epithelium in its outer and middle zones, which are the site of outlet in water pathway, membrance potential and resistance were lower than those in other cells, which indicate that bulk flow of the cell sap from theCapital cells to the outside takes place by intracellular hydrostatic pressure.

Coupling between action potential and bioluminescence inNoctiluca: Effects of inorganic ions and pH in vacuolar sap
A proton hypothesis explains the coupling between the bioluminescence and the action potential in Noctiluca by injecting various salt and pH buffer solutions into the vacuole.
Physiology of Rapid Movements in Higher Plants
This review is not intended to be a comprehensive resume of all published works on the movements, but will return to some of the important older literature which provides a basis for understanding the mechanism.
The Flash-Triggering Action Potential of the Luminescent Dinoflagellate Noctiluca
The findings all indicate that the action potential belongs to the familiar class of responses which have their origin in voltage- and time-dependent selective increases in membrane permeability, and that morphological factors account for the observed deviations from normal behavior.
