Leaves of the Venus Flytrap and Other Sensitive Plants Move

Question

Leaves of the Venus flytrap and other sensitive plants move quickly due to
A) reduced permeability to potassium ions.
B) muscle- like plant cells called myophytes.
C) an electrical stimulus and rapid diffusion of ions out of motor cells.
D) hormones that cause plant cell movement.

Accepted Answer

The rapid movement of Venus flytrap leaves is triggered by an electrical stimulus that causes ions to rapidly diffuse out of specialized motor cells, leading to changes in turgor pressure and resulting in quick leaf movement.
