Detailed explanation-1: -Thigmotropism is a directional growth movement which occurs as a mechanosensory response to a touch stimulus. Thigmotropism is typically found in twining plants and tendrils, however plant biologists have also found thigmotropic responses in flowering plants and fungi.

Detailed explanation-2: -These are examples of how plants respond to touch or wind. The movement of a plant subjected to constant directional pressure is called thigmotropism, from the Greek words thigma meaning “touch, ” and tropism, implying “direction.” Tendrils are one example of this.

Detailed explanation-3: -Thigmotropism is the directional response of a plant organ to touch or physical contact with a solid object. This directional response is generally caused by the induction of some pattern of differential growth. This phenomenon is clearly illustrated by the climbing tendrils of some plants, such as the sweet pea.
