“Plants have feelings, too”
A new study shows plants make noises when stressed.
In an experiment, researchers denied water to some tomato and tobacco plants and cut the stems of others, then they placed microphones nearby.
The microphones picked up noises coming from the plants that humans cannot hear. However, researchers say other animals could detect the sounds from about 10 to 15 feet away.
Previous studies have shown that stressed plants send out other signals — they release chemicals and vibrate when experiencing drought.
In this study, the scientists placed microphones about four inches away from the plants.
“It sounds a bit like popcorn—very short clicks,” one researcher said. “It is not singing.”
