Thigmotropism is the directional response of a plant organ to touch or physical contact with a solid object. The mechanism of thigmotropism is as follows: Common tropic responses in plants include phototropism, gravitropism, thigmotropism, hydrotropism, thermotropism, and chemotropism. For instance, a tendril of the sicyos plant can detect a weight of 0.00025mg, whereas a sundew plant can detect a weight.
