Seed Dispersal Matching Solution
This question requires matching specific plants with their primary modes of seed dispersal. Here is the correct pairing:
| Plant (Column A) | Mode of Dispersal (Column B) |
| 1. Dandelions | c. Wind |
| 2. Lotus | a. Water |
| 3. Mango | d. Animal |
| 4. Castor | b. Explosion |
Reasoning for Matches
- Dandelions: Their seeds have a parachute-like structure (pappus) enabling dispersal by wind.
- Lotus: As an aquatic plant, its seeds are adapted for dispersal by water.
- Mango: The fleshy fruit is attractive to animals, facilitating dispersal by animal consumption and excretion.
- Castor: Castor seed pods can sometimes split open suddenly, ejecting seeds via explosion.
The correct option matching these pairs is 1-c, 2-a, 3-d, 4-b.
