When you cut off a human's appendage, the screaming comes from a voice. The voice comes from a sort of... consciousness. Which while we haven't exactly nailed down what makes one up, we are reasonably certain that it involves a nervous system.

Plants communicate distress using their own kind of nervous system: Model mustard plant uses the same signals as animals to relay distress

Making this absurd for a sec to make my point, I think they’re just saying if the physical sound of an arm being cut off just happened to mimic a human voice crying out, that wouldn’t make it a sign of consciousness like an actual “Ow!” from the speech center.

There’s a difference between a creature’s higher level response to a stimulus and just stuff that happens as a direct physical consequence of the stimulus.

It’s the same deal as boiling live lobsters. They aren’t actually screaming, even if you would be. That’s steam escaping. What the plant sound actually is, no clue. But I think the lobster scenario is what was being suggested upthread.

Literally the only difference between the two scenarios are the amount of complexity of the systems involved. You can describe either one in purely mechanistic terms.

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_.

No it isn’t
