how do grape vines know where to grab posts and other stationary objects if they have no eyes?

My mom has a pergola and every year, the grape vines will wrap itself around it. Sometimes it reaches for objects that are leaning against it (even the chairs!) or it will even grab other plants that aren’t directly towards the sunlight.

How do they know that they can grab these objects as well instead of just wrapping itself around the pergola?

They’re like me at the buffet, reaching for everything within grasp whether they need it or not.
