It seems like Roald Dahl may have been onto something after all: if you hurt a plant, it screams.
Well, sort of. Not in the same way you or I might scream. Rather, they emit popping or clicking noises in ultrasonic frequencies outside the range of human hearing that increase when the plant becomes stressed. This, according to scientists, could be one of the ways in which plants communicate their distress to the world around them.
