Detailed explanation-3: -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-4: -Final Answer: The directional movement of plants in response to contact is thigmotropism.
