It is important to be aware of your environment. You have to predict if there is danger nearby or if there is food in the vicinity. Just as we are able to react to things that happen around us, plants are able to respond to signals in their environment as well. They have to, their environment is changeable and they can’t go elsewhere or move away from the trouble. But what if plants are as blind and deaf as they seem to us? Or is something else going on?
Our hearing is nothing more than the perception of sound waves. Recent investigation suggests that plants can als perceive these waves. A plant has no ears, but feels the vibrations of soundwaves and uses the soil or air as the sound medium. They can perceive the vibrations of running water or some even of the moving wings of insects.
