I think this gets to the conflation we naturally have with consciousness and a sense of self. Does a tree have a sense of self? I imagine probably not, a tree acts more like a clonal colony than a single organism.

Is someone tripped out on mushrooms experience ego death and total disruption of sense of self still conscious? They may even contend they are more conscious than normal life, what with all the communing with the universe and whatnot.

Trees react to the world around them in many ways.
