Vedclass · Answer

(C) Thigmotropism is the directional growth movement of a plant in response to a touch stimulus.It is most prominently observed in the tendrils of climbing plants.When a tendril comes into contact with a solid object (support),the side in contact grows more slowly than the side away from the object,causing the tendril to coil around the support.This adaptation helps the plant climb and gain access to sunlight.
