Researchers uncover mechanism responsible for the world’s most famous carnivorous plant’s snapping jaw
When Charles Darwin first saw a Venus flytrap, he was fascinated. The British naturalist was a pioneer in the scientific study of the carnivorous plant, perhaps the most famous one in the world. Seeing it move so quickly made it seem like an animal. The researcher even thought that there must be some plant equivalent to muscles and nerves. More than a century later, the Venus flytrap continues to challenge scientists’ ideas about plant movement. Now, a team of physicists and biologists have show that the secret to its snapping jaws lies in its capability of modifying the mechanical properties of its cellular walls almost instantaneously, a change that sets off the closure of the leaf around its prey.
