Hint
Recall Figure 7.5 in the chapter — "Leaf of Bryophyllum with buds."
Quick Oral Answer
Bryophyllum reproduces vegetatively — tiny buds form in the notches along its leaf margins, and when these fall onto soil, each one grows into a new, genetically similar plant.
Analysis & Explanation
The NCERT chapter states: "buds produced in the notches along the leaf margin of Bryophyllum fall on the soil and develop into new plants" (Section 7.2.5, Fig. 7.5). This is a classic example of vegetative propagation through leaves.
- (A) Apical buds formed on the tip of the plant — incorrect. Bryophyllum's reproductive buds are not apical (tip) buds; they arise specifically in the notches along the leaf margin, not at the plant's growing tip.
- (B) Vegetative buds produced in the notches of the leaf — correct. This exactly matches the text: buds form in the leaf-margin notches, fall to the soil, and grow into new independent plants.
- (C) Flowers produced in the notches of the branches — incorrect. This confuses vegetative (bud) propagation with sexual reproduction via flowers; Bryophyllum's propagation here is asexual, and the structures are on leaves, not branches.
- (D) Fruits formed on the branches of the plant — incorrect. Fruits result from sexual reproduction (fertilised ovary) and are irrelevant to Bryophyllum's characteristic vegetative propagation method.
Common Mistakes
- 1Confusing vegetative buds with flower buds
- 2Assuming the buds arise at the shoot tip rather than the leaf margin
Interesting Facts
Bryophyllum is a well-known example of a plant that can propagate itself vegetatively without needing seeds, similar in principle to potato tubers reproducing via 'eyes' (notches with buds), as explored in Activity 7.5.
