(NaturalNews) Plants are able to tell different insect predators apart, both by sensing the different shapes of their jaws, and by "hearing" the different vibrations caused by their chewing, according to recent research by Heidi Appel of the University of Missouri.
This allows the plants to respond with defensive measures tailored to a specific attacker, Appel said.
Because plants are not able to flee from predators the way animals can, they have evolved a complex suite of defenses to deter herbivores and parasites. Many of these involve chemical defenses that are only activated when an attack occurs.
"[Plants] are way more clever than we give them credit for," Appel says.
