New study shows that plants can respond to sounds to find water
A new study by scientists from the University of Western Australia has discovered that plants have the ability to respond to sounds to find water to survive.
The researches in their study demonstrated how 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.
Using the pea plant as the model for study, the scientists put the plant in a container that had two test tubes at the base, giving it a choice of two directions for the growth of its roots.
“We then exposed the plant to a series of sounds, including white noise, running water and then a recording of running water under each tube, and observed its behaviour,” said Gagliano, while speaking to Physics.org.
The scientists found that the plants could tell where the …read more
