Certain plants produce audible sound through cavitation under water stress
the verdict
SUPPORTED
the evidence backs this
confidence 86/100
Multiple studies demonstrate that plants emit acoustic signals—frequently detected as ultrasonic acoustic emissions—resulting from xylem cavitation caused by water stress or drought.
