i can prove that plant is exactly like humans, or animals
if you remove the brain from the animal, or the human, he will be like a plant, useless, just a body, just a structure,
and i know what you mean teh difference between alive, and living,
i can feal it, but, the feal is not always true, what a human or an animal ecauls without a brain,
anyway, there are some plants, that eat fly, and other insects, with some kidna of reactions,
as for the gellyfish, it's not an animal, it's a structure, it's liek a moving colony, the big cover of teh jellyfish, is just a roof, what under it, is many little creature,s or organisms, each of them have a role, they are like many creatures stuck together under one roof, like a family, but the jelyfish don't have a brain, it's just a thing, cant call it alive, as a jellyfish, it's not alive, but as what's under it, it is alive,
