Do plants have a sweet-tooth like humans?

A sweet-tooth usually refers to a craving. And cravings are a complex behavior that usually involves the workings of the nervous system. And since plants are not known to have a nervous system, I would say that they do not have the urges associated with cravings, like a sweet-tooth. But who knows? Maybe they have something like a sweet-tooth where they crave a certain mineral that is not available to them in the soil. Maybe that's how the Venus Flytrap developed its unique ability to trap and digest flies.
