Dodder Vine Sniffs Out Its Prey

Clip: Season 31 Episode 9 | 2m 33s

Unable to produce its own food, the dodder vine must live entirely off a host plant. In a series of experiments, Researchers Consuelo M. De Moraes and Mark Mesker show that to find a host plant from which to drain nutrients, the parasitic plant "sniffs" out the chemical scents released by the leaves of nearby plants. "What Plants Talk About" premieres April 3 at 8/7c (check local listings).
