The names of some of the plants are given below :
Xanthium, Castor, Drumstick, Urena, Balsam, Maple, Grass, Madar (oak), Coconut, Sunflower
Which of these seeds/fruits are dispersed :
by wind?

Answer

To determine which of the listed seeds or fruits are dispersed by wind, we can analyze each plant's characteristics regarding seed dispersal mechanisms.

### Step-by-Step Solution:

1. **Understand Seed Dispersal**: Seed dispersal is the process by which seeds are spread away from the parent plant to reduce competition and increase the chances of germination. One common method of dispersal is by wind.

2. **Identify Plants**: The plants mentioned in the question are:
- Xanthium
- Castor
- Drumstick
- Urena
- Balsam
- Maple
- Grass
- Madar (Oak)
- Coconut
- Sunflower

3. **Analyze Each Plant**:
- **Xanthium**: Known for its lightweight seeds with hooks, which can be carried by the wind.
- **Castor**: Seeds are relatively heavy and not primarily wind-dispersed.
- **Drumstick**: The seeds are not adapted for wind dispersal.
- **Urena**: Seeds are not typically wind-dispersed.
- **Balsam**: Has a mechanism for explosive seed dispersal, not wind.
- **Maple**: Has winged seeds (samaras) that are easily carried by the wind.
- **Grass**: Grass seeds are lightweight and can be dispersed by wind.
- **Madar (Oak)**: Acorns are heavy and not wind-dispersed.
- **Coconut**: While coconuts can float and travel by water, they are not primarily wind-dispersed.
- **Sunflower**: Sunflower seeds can be dispersed by wind due to their lightweight nature.

4. **List the Plants Dispersed by Wind**: Based on the analysis, the plants whose seeds/fruits are dispersed by wind are:
- Xanthium
- Maple
- Grass
- Sunflower

### Final Answer:
The seeds/fruits that are dispersed by wind from the given list are: **Xanthium, Maple, Grass, and Sunflower.**
