Options
Official answer
d
Marking scheme
- 1.1 Mark for identifying option (d) as the incorrect match.
Hint
Think about how roses are commonly propagated in gardens using stem cuttings rather than roots.
Quick oral answer
Rose is propagated vegetatively through stem cuttings or grafting, not through its roots. Therefore, 'Rose, root' is the incorrect match.
Common mistakes
- 1.Students often mistake potato as a root because it grows underground, but it is biologically a modified stem.
Analysis and explanation
In vegetative propagation, new plants are developed from vegetative parts like roots, stems, or leaves.
- Option (a) Bryophyllum, leaf: Correct match. Bryophyllum reproduces vegetatively through buds produced along its leaf margins.
- Option (b) Potato, stem: Correct match. Potatoes are modified underground stems (tubers) containing vegetative buds or 'eyes' that give rise to new shoots.
- Option (c) Money-plant, stem: Correct match. Money-plants can grow from stem cuttings containing at least one node/leaf.
- Option (d) Rose, root: Incorrect match. Roses are propagated vegetatively using stem cuttings or grafting, not roots. Therefore, this is the incorrect pair.
Interesting facts
Bryophyllum is also known as the 'miracle leaf' because miniature plantlets with tiny roots develop directly on the margins of the parent leaf, falling off to grow into independent plants.
