It's still just physics and chemistry all the way down though. It's not clear that plants couldn't evolve something similar through a mechanism other than a nervous system.
Okay but - and I can't believe that I actually have to say this - it is pretty clear that they _haven't_.
Informative here meaning that you can deduce something about a plant's condition from faint sounds emitted by it. It's not implying that the plants use those sounds for the purpose of transmitting information. From the article: "These results demonstrate the potential in studying plant bioacoustics, suggest that plant acoustic emissions may play an important role in ecology and evolution, and may have direct implicat…
I am astounded that no one has mentioned "The Sound Machine" by Roald Dahl (1949), in which a scientist invents a machine that makes ultrasonic sounds audible to humans. He discovers that plants scream when cut. You can read it at https://www.newyorker.com/magazine/1949/09/17/the-sound-mach...

If the signal is being sent, you can be pretty sure that due to the intrinsic efficiency-maximization that biological systems perform then most likely the mechanism for detecting and acting upon it has been evolved by other organisms, especially for something as fitness-critical as stress.
I'm not sure why you can assume that without any direct evidence.
How about this claim: pieces of string when stressed emit sounds that are picked up by nearby strings. Should be investigate this claim? What does it mean that the world of string acts this way. For those that haven't witnessed it, I will describe a very easily constructed experiment to demonstrate this phenomena that I have discovered: first stretch a string tightly and then quickly flick it with your finger, stress…
Plants are incredibly complex yet people roll their eyes at the idea of them doing anything besides nothing. Maybe because it undermines the idea of veganism. idk, sorry lesser beings i'm hungry.
