Plant Self-Defense
Clip: Season 31 Episode 9 | 1m 8s
To protect against herbivores, wild tobacco plants deposit sweet but deadly secretions.
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).
