Researchers Record Plants Emitting “Sounds” When Uprooted in Groundbreaking Discovery

Scientists at Tel Aviv University in Israel have discovered that plants produce sounds in ultrasonic frequencies, outside the range of human hearing. Researchers captured the sounds of plants “screaming” when they were harvested, describing them as a polling or clicking noise that increased when the plant was under stress. Lilach Hadany, an evolutionary biologist at the university, explained that plants interact with insects and other animals on a regular basis and use sound for communication, so it made sense for them to also produce sounds when stressed. The team recorded tomato and tobacco plants in stressed and unstressed conditions and found that distressed plants emitted high-pitched sounds that were undetectable by humans but could be heard within a radius of over a meter. Unstressed plants did not produce much noise at all. While the exact mechanism through which plants produce these noises is still unknown, this study sheds light on an intriguing aspect of plant biology and opens up new possibilities for understanding the ways in which plants communicate with their environment.
