Model Answer

This illustrates that leaves are capable of vegetative propagation, as buds produced at the leaf margins of Bryophyllum fall on soil and develop into new plants.

Explanation

The question directly targets the Bryophyllum example from Activity 7.5/7.2.5. The key term examiners look for is "leaves" (or "leaf margins"). Mentioning that the buds fall on soil and grow into new plants adds completeness for a 1-mark answer and shows understanding, not just recall.
