Vedclass · Answer

(B) Thigmotropism is the directional growth movement of a plant in response to a touch stimulus. Tendrils are specialized structures in climbing plants that exhibit a high sensitivity to touch. When a tendril comes into contact with a support,the cells on the side opposite to the contact grow faster than the cells on the contact side,causing the tendril to coil around the support. Therefore,tendrils are the best example of thigmotropism.
