Question

Answer

In some plants, the subaerial stems are modified for the purpose of vegetative reproduction. They are of different types like runners, offset, stolons and suckers.

The runner arises from the base of the stem as a lateral branch and runs along the surface of the soil. It develops distinct nodes and internodes. At each node, the runner produces roots below and leaves above e.g., Oxalis, Fragaria etc.

An offset is a short runner like the branch which produces the new plant at its tip. The offset grows in all direction from the main stem of parent plant usually along the surface of the water. If separated from parent plant offset can grow in an independent plant e.g., Pistia, Eichhornia.

Stolons are lateral branches that arise from the stem above the soil for a certain distance. When the tip touches the ground at the nodal region, it produces a new plant. As the plant grows the stolons grow horizontally outward for a varying distance in the soil.Ultimately their end emerges out of the ground and develops into a new plant e.g., Mentha, Rosaceae.

A lateral branch arising from main stem close to the ground level travels underground for some distance. This branch is called a sucker. It turns up at its end and produces adventitious roots in the ground and shoots above forming a new plant. Chrysanthemums, mainly cultivated for its beautiful flowers propagates through suckers.

Answer

Correctly Matched Pair: Sucker - Chrysanthemum

Explanation:
Sucker and Chrysanthemum is the correctly matched pair out of the given options. Let's understand the meaning of both terms and why they are correctly matched.

Sucker:
- A sucker is a type of vegetative propagation in plants where new shoots arise from the base of the stem or from the roots.
- Suckers are produced by the lateral buds present on the underground stems or roots of a plant.
- These lateral buds grow into new shoots, which can develop into new plants if they are separated from the parent plant.

Chrysanthemum:
- Chrysanthemum is a flowering plant that belongs to the Asteraceae family.
- It is a popular ornamental plant known for its beautiful and colorful flowers.
- Chrysanthemums are propagated through various methods, including suckers.

Why is the pair correctly matched?
- Chrysanthemums can be propagated through suckers, which means new plants can be grown from the lateral buds on the underground stems or roots.
- When the suckers are properly separated from the parent plant and planted in suitable conditions, they can develop into independent chrysanthemum plants.
- This method of propagation through suckers is commonly used by gardeners and horticulturists to propagate chrysanthemums and create new plants.

Conclusion:
The correctly matched pair is 'Sucker - Chrysanthemum' because chrysanthemums can be propagated through suckers, where new shoots arise from the lateral buds on the underground stems or roots of the parent plant.
