Water hyacinth is a free floating perennial plant, which can grow to a height of 3 feet.

Pairs of Organisms with their Correct Characteristics:

a) Penicillium - Conidia
b) Water hyacinth - Runner
c) Bryophyllum - Leaf buds
d) Agave - Bulbils

Explanation:

Penicillium - Conidia:
- Penicillium is a type of fungus that belongs to the group Ascomycetes.
- It reproduces asexually by forming specialized structures called conidia.
- Conidia are small, asexual spores that are produced at the tips of specialized hyphae called conidiophores.
- These conidia are dispersed by air and are responsible for the rapid spread of Penicillium.

Water hyacinth - Runner:
- Water hyacinth is a floating aquatic plant that belongs to the family Pontederiaceae.
- It reproduces vegetatively by producing specialized stems called runners or stolons.
- Runners are horizontal stems that grow along the surface of the water, producing roots and new plants at each node.
- This method of reproduction allows water hyacinth to rapidly colonize new areas of water bodies.

Bryophyllum - Leaf buds:
- Bryophyllum is a succulent plant that belongs to the Crassulaceae family.
- It reproduces vegetatively by producing specialized structures called leaf buds.
- Leaf buds are small outgrowths that form at the margins of the leaves.
- These leaf buds can detach from the parent plant and develop into new individuals when they come into contact with soil.

Agave - Bulbils:
- Agave is a plant genus that belongs to the family Asparagaceae.
- It reproduces vegetatively by producing specialized structures called bulbils.
- Bulbils are small, bulb-like structures that develop in the axils of the leaves or at the ends of the flower stalks.
- These bulbils can detach from the parent plant and develop into new individuals when they come into contact with the ground.

Conclusion:
The wrongly matched pair is b) Water hyacinth - Runner. Water hyacinth reproduces vegetatively through runners, not by forming bulbs.
