Did You Know? Thirsty Plants 'Scream' in Ultrasonic Sounds!
Plants are not silent sufferers; when stressed by dehydration or cutting, they emit ultrasonic clicks and pops that are undetectable to the human ear, akin to "screams."
Recent groundbreaking research, utilizing specialized microphones, has revealed that plants under various forms of stress, such as dehydration or stem cutting, produce a surprisingly high number of airborne ultrasonic sounds. These distinct noises, ranging from 20 to 100 kilohertz, are not random; they carry information and vary depending on the type and severity of stress. While their precise ecological function is still being investigated, scientists hypothesize these sounds could potentially be a form of communication, alerting nearby plants or even attracting/repelling animals like moths or bats, thereby unveiling a previously hidden auditory dimension of nature.
