Researchers found out the plants, like humans, have "Immune System" that helps it fight infections. In a series of laboratory experiments, researchers found out that plants are able to fight infections by secreting beneficial chemicals from the soil through it's roots.

The finding quashes the misperception that plants are “sitting ducks”--at the mercy of passing pathogens--and sheds new light on a sophisticated signaling system inside plants that rivals the nervous system in humans and animals.

“Plants are a lot smarter than we give them credit for,” says Bais from his laboratory at the Delaware Biotechnology Institute.

“People think that plants, rooted in the ground, are just sitting ducks when it comes to attack by harmful fungi or bacteria, but we've found that plants have ways of seeking external help,” he notes.
