without altering or stretching the definition of the word even in the slightest. The word "pain" has the concept of the mental experience of suffering pretty much baked in to it. Applying it to plants seems to very much stretch the definition when there is literally no biological structure in plants that corresponds to the neural activity organisms with a CNS when experiencing pain. An electrical pulse isn't really sufficient: plants send electric signals under a variety of circumstances. Pain isn't merely a response to negative stimuli. That does stretch the definition.
