Which plant structure can coil around a support after touching it?
Answer and explanation
Correct answer: Tendril
The governing concept is a tendril’s touch-guided growth response. A tendril is a slender, specialised structure that bends and coils when it contacts a support, helping the plant climb and obtain better light. A main root anchors and absorbs water, a petal attracts pollinators, and a cotyledon stores or supplies nourishment to the young seedling. Thus option A is correct.
