Sentience in Plants: Plants Respond to Sound of Chewing Caterpillars

Sentience in Plants:  Plants Respond to Sound of Chewing Caterpillars | GarryRogers Biosphere News | Scoop.it
Previous studies have suggested that plant growth can be influenced by sound and that plants respond to wind and touch. Now, researchers at the University of Missouri, in a collaboration that brings together audio and chemical analysis, have determined that plants respond to the sounds that caterpillars make when eating plants and that the plants respond with more defenses.
Garry Rogers's insight:

GR:  Plants don't share many of the traits we associate with intelligence in animals.  Like animals, however, they can act to defend against injury. They can move their leaves and stems, and they can produce repellant chemicals.

Scientists usually view plants as static forms that build defenses as natural selection acts on reproductive success.  The traits associated with plant growth, reproduction, and dispersal are sometimes called strategies, but not in the sense that foresight and planning are involved. Considering the limited sentience plants exhibit, this seems appropriate.  Still, it would be interesting to devise an IQ test for plants.  We could find out which ones are the most sagacious.
