"WebPART H: Closure of the flytrap requires APs to initiate the contraction process inside the leaves of the flytrap. In Dionaea, the action potentials cause K+ to move from the center of the flytrap to the outer leaves, and water follows (fluid movement). This shift creates a low fluid pressure region at the base of the capture organ. " - Resting action potential
