“Everyone knows that plants react to light, and scientists also know that plants use volatile chemicals to communicate with each other, for instance, when danger - such as a herbivore - approaches,” Dr. Gagliano said in a university news release.
- plants not only respond to sound, but they also communicate to each other by making “clicking” sounds.
- researchers at The University of Western Australia were able to hear clicking sounds coming from the roots of corn saplings.
- when they suspended the young roots in water and played a continuous noise at 220Hz, a similar frequency to the plant clicks, they found that the plants grew towards the source of the sound.
