I certainly behave as though plants do not experience pain.

However: plants are only noticeably animate in time-lapse footage, and have no mouth with which to scream.

I have no idea why the particular electrochemical properties of the neurotransmitter exchange membranes in my body are able to give rise to qualia, so without that I can't rule out plants doing that but very slowly.

Of course, if they do, then my skin may have an independent qualia to my kidneys let alone to what I call "me", so as you say, I don't live my life as if it were so.
