Does sentience require a CNS? If yes, sponges and jellyfish don’t suffer? If no, damaged plants release chemical distress signals. They alter behavior (growth patterns, resource allocation) to avoid damage. They prime defensive responses after initial exposure, functionally similar to sensitization. Root tips show oscillatory electrical activity that some researchers compare to neural activity. So plants have no neurons but do have sophisticated signaling. Yet you think they don’t suffer? Given that we don't understand consciousness, how can you be certain enough about plant insentience to justify killing them without moral concern?
