Scientists have found that plants can make sounds.
A scientist, Lily Hadany, and her team recorded(录制) tomato plants at different times. It showed that the plants made ultrasonic(超声波) sounds. People could only hear them with the help of a computer. They were noises like clicking(发出咔嗒声) sounds.
As scientists studied the sounds, they began to find some interesting facts. Plants made different sounds at different time. They seldom clicked when they had enough water, but when they needed water, they clicked more and more. Scientists also found that plants made sounds when they got hurt. When scientists cut off a leaf from the plants, the plants also clicked more. But this kind of clicking wasn't the same as when the plants needed water.
Some scientists designed a computer AI system to tell the different kinds of clicking sounds. It was able to find the difference between plants that needed water and plants with cuts. It means that one day we may be able to use these sounds to figure out when it is in difficult time, and what problem it is having. That could be very helpful to farmers.
The team's finding changes our ideas about plants. As Dr Hadany says, "Even in a quiet field, there are sounds made by plants, and those sounds carry information and may help us a lot. "
