Detailed explanation-1: -The movement of plant due to touch is known as a thigmotropic movement. Thigmotropism is a directional growth movement which occurs as a mechanosensory response to a touch stimulus. For example, once a shoot touches a suitable support, it grows towards the surface it is touching.

Detailed explanation-2: -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.

Detailed explanation-3: -Thigmotropism is when a plant will respond to touch from an external source. The plant will move toward or away from the contact stimulus. When the plant moves toward the stimulus, it is called positive thigmotropism. An example of positive thigmotropism is when a tendril on a climbing plants coils around a fence.

Detailed explanation-4: -thigmotropism: plant growth or motion in response to touch. thigmomorphogenesis: the response by plants to mechanical sensation (touch) by altering their growth patterns.

Detailed explanation-5: -Also referred to as haptotropism, thigmotropism is the movement or change in orientation of a plant’s growth as a reaction to touch. The orienting factor is generally a hard surface that can change the direction of the plant’s growth or the growth of one of its organs.
