A tendril coiling around a support after touching it is an example of what?
Answer and explanation
Correct answer: Thigmotropism
Thigmotropism is directional growth caused by contact or touch. When one side of a tendril touches a support, unequal growth makes it curve and coil around that support, so option A is correct. Phototropism is guided by light, hydrotropism by water, and geotropism by gravity. The essential stimulus in this example is physical contact with the support.
