I mean, when I compare an animal to a plan, the primary difference is that the plant "moves" much slower; My little bird without water, or in the cold, will face problems sooner than the tree that's growing beside him - but either would die, without attention.
If the plant is communicating, I simply can't hear or see it; But plants constantly change their "aura" depending on time of day, or the condition their in.
That's powerful stuff.
Mostly unexplored it seems.
