Find the set that correctly matches the plants in column A with the mode of asexual reproduction which they exhibit :
| Column A | Column B |
|---|---|
| (a) Rose | (i) Budding |
| (b) Yeast | (ii) Spore formation |
| (c) Ferns | (iii) Fragmentation |
| (d) Spirogyra | (iv) Pollination |
| (v) Vegetative propagation |
Answer: A
The correct matching is (a)-(v), (b)-(i), (c)-(ii), (d)-(iii).
- Rose: vegetative propagation, by stem cuttings.
- Yeast: budding, a small bud growing from the parent cell.
- Ferns: spore formation.
- Spirogyra: fragmentation, the filament breaking into pieces that each grow.
Pollination is not a mode of asexual reproduction at all; it is a step in sexual reproduction, so options matching any plant to pollination are wrong, and option C swaps the yeast and Spirogyra methods.
