> Plants don't have a central nervous system or a brain. What science generally understands under pain and suffering plants simply don't have.
Quite a number actually do have nervous systems [0], using neurotransmitters that have actually been found in mammals. They respond to wounding, both with efforts to repair it, and with chemical deterrents to the cause.
Now, that isn't to say that they necessarily have pain and suffering, but it wouldn't be surprising to learn that some plants possess that capability.
I have no idea where the ethical line ought to be here, but if plants have meaningful capacity to suffer then it’s also likely that PETA should be campaigning to limit the mistreatment of even the tiny AI we make while doing MOOCs on the basics of machine learning.
