thigmotropism
A plant that responds to touch is exhibiting thigmotropism. Thigmotropism is a response where a plant changes its growth pattern in response to touch or contact with a solid object.
Thigmotropism - tendrils of climbers exhibit a positive thigmotropism by growing towards and wrapping around a support structure to aid in climbing and anchoring the plant.

The growth of a vine around a post is an example of thigmotropism, which is a plant's response to touch or contact with a solid object. Gravitropism, on the other hand, is a plant's response to gravity, causing roots to grow downward and shoots to grow upward.
Thigmotropism is the growth response of plants to contact or mechanical stimulation. Examples include vines wrapping around a support structure and tendrils coiling around objects for support. These plants exhibit thigmotropism as a way to seek structural support for growth.
