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: -This is a type of rapid plant movement called thigmonasty or seismonasty or haptonasty and comes as a direct reaction to physical contact.

Detailed explanation-3: -Thigmotropism is the type of tropic movement which occurs in response to touch. Similarly, phototropism, chemotropism and hydrotropism occur in response to light, chemicals and water respectively.

Detailed explanation-4: -Thigmotropism is similar to touch in humans. Thigmotropism is when a plant responds to a movement or touch from another stimulus. This stimulus is known as a contact stimulus.

Detailed explanation-5: -Thigmotropism : The touch-me-not (Mimosa pudica) plants exhibit the phenomenon of thigmotropism where the leaves droop on being touched by a finger or an object. The phenomenon of directional movement of the plant parts in response to the stimulus of contact or touch with a solid surface is known as thigmotropism.
