Incorrect Pairing:
b) Water hyacinth - Runner
Explanation:
Water hyacinth (Eichhornia crassipes) is a free-floating aquatic plant that belongs to the family Pontederiaceae. It is an invasive species that can rapidly spread in bodies of water, causing ecological problems.
Water hyacinth reproduces vegetatively through a process called stoloniferous propagation, not through runners.
Stoloniferous Propagation:
- Water hyacinth produces specialized horizontal stems called stolons that grow horizontally along the surface of the water.
- These stolons have nodes where new plants can develop.
- At each node, small daughter plants, known as plantlets, are formed.
- These plantlets are connected to the parent plant by a thin stalk.
- Eventually, the plantlets grow roots and detach from the parent plant, becoming independent individuals.
The plantlets formed through stoloniferous propagation are responsible for the rapid spread of water hyacinth in water bodies. They are easily carried by currents, wind, or human activities, and can quickly colonize new areas.
Conclusion:
The correct pairing for water hyacinth would be stoloniferous propagation, not runners. Therefore, option b) Water hyacinth - Runner is wrongly matched, while the remaining three pairs are correct.
