An Israeli study has shown that plants make sounds when they are stressed.So why has no one ever reported hearing them? That's because the sounds that the plants are making are too high for humans to hear. Humans usually hear up to around 16 kilohertz(千赫). Plant sounds start from arou...
Scientists 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.As the scientists studied the sounds, they be...
they had enough water, but as the earth got drier, 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 the clicking wasn’t the same as when the plants needed ...
Plants make sounds when they are in pain or in stress, especially when deprived of water or are forced to endure bodily harm.
Now scientists have created a quick way to understand what plants are saying:a chemical sensor(传感器)called an electronise nose,The“e-nose”can tell compounds that crop plants make when they’re attacked.Seientists say the e-nose could help quickly detest whether plants are being eaten by ...
A study shows that plants make sounds when they are stressed.Scientists in Israel did the study. They used ultrasonic microphones to record (记录) the sounds of tomato plants in boxes. They listened to three groups of plants.The first two groups made sounds 30 to 50 times every hour. The...
根据第四段中 "Some scientists trained a computer Al system to identify the different kinds of sounds. It could find the difference between plants that needed water and plants with cuts. "可知,一些 科学家训练了一个计算机人工智能系统来识 别不同种类的声音。 它可以发现需要浇水的 植物和有伤口的...
Plant lovers help plants grow by talking to them. Scientists from Israel believe plants may be able to talk back. Researchers found that plants make sounds like a human scream when they are stressed. We may be able to interpret the sounds and give plants what they need. However, the sounds...
The "e-nose" can tell compounds that crop plants make when they're attacked. Scientists say the e-nose could help quickly detest whether plants are being eaten by insects But today the onlyway to detect such insects is to visually inspect individual plants. This is a challenging task for ...
