Question:
Main dispersal agent of Dandelion is _____.
Main dispersal agent of Dandelion is _____.
Show Hint
Anemochorous seeds are lightweight and have specialized aerodynamic structures like hairs (pappus in dandelions) or wings (as in pine or maple seeds).

The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Weed seed dispersal is the movement of seeds away from the parent plant.
Weeds rely on several dispersal agents: wind (anemochory), water (hydrochory), animals (zoochory), or mechanical self-projection (autochory).
Step 2: Detailed Explanation:
The dandelion (*Taraxacum officinale*) is a classic example of a wind-dispersed weed (anemochory).
It has evolved specialized structures to maximize wind transport:
1. Each individual flower in the flower head produces a single-seeded fruit called an achene.
2. Attached to the top of each achene is a fine, hair-like parachute structure called a pappus.
3. When the seeds mature, the flower head opens into a white, spherical puffball.
Even a gentle breeze can catch the pappus, lifting the seed and carrying it over long distances.
This efficient wind dispersal allows dandelions to colonize open ground, lawns, and agricultural fields very quickly.
Dispersal by water, birds, or humans can occur occasionally, but wind is the primary, specialized agent of dispersal.
Step 2: Final Answer:
The main dispersal agent of Dandelion is Wind.
