WebThigmotropism is a movement in which a plant moves or grows in response to touch or contact stimuli. The prefix thigmo- comes from the Greek for "touch". Usually thigmotropism occurs when plants grow around a surface, such as a wall, pot, or trellis. Climbing plants, such as vines, develop tendrils that coil around supporting objects. http://tomatosphere.letstalkscience.ca/Resources/library/ArticleId/4973/tropisms-in-plants.aspx
