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.
it’s funny because ants in actuallity can’t see very well and rely on a scent line left by other ants to make their way back. if that line is obstructed, they wait for another ant to come along and lay out an alternate route.
