Question

Match the columns:

Column A	Column B
$1 .$ Eyes	(a) Spirogyra
$2 .$ Spores	(b) Yeast
$3 .$ Wings	(c) Potato
$4 .$ Bud	(d) Bread mould
$5 .$ Fragmentation	(e) Maple

Accepted Answer

1 - (c)
A potato is a modified stem with buds called eyes on its surface. These buds develop into a new plant.

2 - (d)
The tiny blob-on-a-stick structures are involved in reproduction. The blobs are sporangia, which contain cells, or spores, that can eventually develop into new Rhizopus individuals. The spores are covered by thick walls that protect them until they come into contact with another moist surface and can begin to grow.

3 - (e)
Seeds of plants like maple have wings. These seeds get blown away to different places by wind. The wings help in dispersal of the seeds.

4 - (b)
In yeast, the division is unequal and small buds are produced that remain attached initially to the parent cell which, eventually gets separated and mature into new yeast organisms.

5 - (a)
Spirogyra is algae which reproduces by fragmentation. In multi-cellular organisms with relatively simple body organisation, simple reproductive methods can still work. Spirogyra, for example, simply breaks up into smaller pieces upon maturation. These pieces or fragments grow into new individuals.
Thus, the final answer is:

1. Eyes (c) Potato

2. Spores (d) Bread mould

3. Wings (e) Maple

4. Bud (b) Yeast

5. Fragmentation (a) Spirogyra
