As far-fetched as it may sound, some plants can actually hear. In fact, it has been scientifically proven by researchers that plants are perfectly capable of setting up defense mechanisms responding to sound. They discovered that when the sound of a specific predators is played near the plant, their defense mechanism to fight against insects are triggered. Let’s look a little closer. These researchers first observed, how plants of the Arabidopsis genus, plants related to mustard and cabbage, reacted when a caterpillar nibbled at their leaves.    See acast.com/privacy for privacy and opt-out information.
