It may sound like the title of a B-grade horror flick, but a recent study indicates that plants can indeed 'scream'.
While naysayers may scoff at that, some studies appear to indicate that there is some truth to the claim. However, a more interesting question is if you can actually get a response.It may sound like the title of a B-grade horror flick, but a recent study by researchers at Tel Aviv University indicates that plants are indeed capable of"screaming".
This is way above the threshold of human hearing, which only goes up to 20kHz. This means it is too high-pitched for humans to hear . What they found was that healthy plants would only make one noise per hour. Whereas unhealthy plants or those under stress made dozens of sounds per hour. Another hypothesis is that other plants near them might be able to 'hear' the sounds and somehow provide aid to the afflicted plant.
