A study led by The University of Western Australia has found plants have far more complex and developed senses than we thought with the ability to detect and respond to sounds to find water, and ultimately survive.

In the study “Tuned in: plant roots use sound to locate water” published in Oecologia, UWA researchers found that plants can sense sound vibrations from running water moving through pipes or in the soil, to help their roots move towards the source of water. The study also revealed that plants do not like certain noises and will move away from particular sounds.

Lead researcher Dr Monica Gagliano from UWA’s Centre of Evolutionary Biology at the School of Animal Biology said water was a basic need for a plant’s survival, and the study showed that sound plays a significant role in helping plants cater to this need.

“We used the common garden pea plant (Pisum sativum) as the model for our study and put the plant into a container which had two tubes at the base, giving it a choice of two directions for the growth of its roots.
