Do plants react to damage?
Immune-like response Plants have no immune system or blood that can coagulate. Their response to damage is instead based on molecular signal mechanisms that act both locally in damaged cells and more peripherally in other parts of the plant. The way plants respond to injuries isn’t an example of pain, but rather, an example of a defense mechanism. Plants, like humans, have evolved ways to defend themselves against external threats, and while our defense involves a pain sensation, theirs does not.Plants efficiently respond to injury and often restore the lost organ.
