Detailed explanation-1: -Rapid plant movement encompasses movement in plant structures occurring over a very short period, usually under one second. For example, the Venus flytrap closes its trap in about 100 milliseconds.

Detailed explanation-2: -The Venus flytrap takes just 100 milliseconds to snap up its prey, one of the fastest movements in the plant kingdom. The biochemical response of the trigger hairs to stimuli and the way that an action potential propagates across the leaves are well known.

Detailed explanation-3: -On the inner surfaces of the lobes are hair-like projections called trichomes that cause the lobes to snap shut when prey comes in contact with them. This type of movement is called thigmonasty-a nondirectional plant response to being touched.

Detailed explanation-4: -The insect-trapping movement of the plant Dionaea muscipula (Venus’s fly-trap) is mediated by the stimulation of mechanosensory hairs located on the surface of the trap. It is known that stimulation of the hairs is followed by action potentials which are propagated over the surface of the trap.

Detailed explanation-5: -Transmission of a single electrical charge between a lobe and the midrib causes closure of the trap and induces an electrical signal propagating between both lobes and midrib. The Venus flytrap can accumulate small subthreshold charges, and when the threshold value is reached, the trap closes.
