Plants were original created for creature sustenance. Our schools have so warped our thinking that this distinction is lost on many. There is common sense difference between a creature with blood that dies and a plant that withers like our skin cells.
What about venus fly traps? What about poison ivy?
They are systems with mechanisms, but we don't think of dead skin cells as the death of a "creature".
Plants are distinct organisms. Skin cells are part of an organism. Big difference.
Our schools have so warped our thinking that this distinction is lost on many.
You seem to be the one who can't make the distinction between organs and organisms.
