Vetches and passion flowers have modified some of their leaves and converted them into tendrils. These grope around in space until they touch the stem of another plant and swiftly coil around it. The tendrils then coil and pull the plant up towards the sunlight.

This is both kind of cool and kind of scary at the same time. The soundtrack to a horror movie is playing in my head right now.
