What Plants Talk About
Video: Plant Self-Defense

To protect against herbivores, the wild tobacco plant deposits trichomes, sweet treats irresistible to but also potentially fatal for leaf-eating caterpillars. Shortly after ingesting the trichomes, the insect releases a particular odor that attracts ground-foraging predators. “What Plants Talk About” premieres Wednesday, April 3 at 8/7c on PBS (check local listings). (Video limited to US & Territories).

    Really bad science, plants are reactive, they do not have the ability to have behaviors. You should be ashamed to present this kind of nonsense. What’s next, intelligent design?

  • Gerhard

    … and what plant/animal is NOT reactive? Are you suggesting that somehow animals operate in a vacuum such that the environment only reacts to them?

    A behavior is any action that can be described as conditional based on input/data from the environment.
