"Scientists Hear Plants Produce Loud Screams when Damaged" (Petrov)


Scientists Hear Plants Produce Loud Screams When Damaged”, video by What Da Math by Anton Petrov.

There is a legend that a mandrake root is pulled, it emits a scream that kills the animal that pulled it.


The paper by Katherine Wu in Smithsonian is here, based on this Biorxiv abstract.

The sounds are ultrasonic, way above human hearing but bats might be able to hear it.  The sounds are generated by bubbles.
  
The video is associated with the Team Trees project (John Fish video). High school biology teachers will love this one.
