AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
The side away from the stick grows faster, because the part in contact with the support grows less rapidly than the part away from it.
As a result of this difference in growth rate, the tendril curves and circles around the object, allowing it to cling to the support.

The examiner expects two clear points: (1) identify which side grows faster, and (2) state the result (curling/coiling around the support). The source passage directly states both facts. Avoid adding extra detail about auxins here — the question is about tendrils specifically, and a concise two-point answer is all that is needed for 2 marks.
