This position holds that plants possess a form of consciousness. Proponents point to the way plants sense light, gravity, touch and chemical signals, communicate through underground root networks, and adapt their behaviour, arguing that awareness need not require a brain.

This position holds that plants are not conscious. Critics argue that sensing and signalling are automatic biochemical responses, that plants lack any nervous system in which experience could arise, and that talk of plant awareness is metaphor mistaken for evidence.
