The Dodder

The parasitic dodder plant doesn't have a nose, but it knows how to sniff out its prey. The dodder attacks such plants as tomatoes, carrots, onions, citrus trees, cranberries, alfalfa and even flowers, and is a problem for farmers because chemicals that kill the pesky weed also damage the crops it feeds on. So discovering how it finds its prey might help lead to a way to block the weed, or for crops to defend themselves, say researchers at Pennsylvania State University.
