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

Answer

To determine which seeds or fruits from the given list are dispersed by water, we can follow these steps:

### 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 survival and growth.

2. **Identify Dispersal Methods**: There are several methods of seed dispersal, including wind, water, animals, and mechanical means. In this case, we are focusing on water dispersal.

3. **Characteristics of Seeds Dispersed by Water**: Seeds or fruits that are dispersed by water typically have the following characteristics:
- They are lightweight or buoyant, allowing them to float on water.
- They often have a structure that helps them stay afloat.

4. **Analyze the Given Plants**: Now, let's look at the list of plants provided:
- Xanthium
- Castor
- Drumstick
- Urena
- Balsam
- Maple
- Grass
- Madar (Aak)
- Coconut
- Sunflower

5. **Identify Suitable Candidates**: From the list, we need to identify which of these plants produce seeds or fruits that can float on water:
- **Coconut**: Coconuts are known for their ability to float on water due to their fibrous husk, which allows them to be dispersed across water bodies.

6. **Conclusion**: Based on the analysis, the only plant from the list that has seeds or fruits dispersed by water is **Coconut**.

### Final Answer:
**Coconut** is the plant whose seeds/fruits are dispersed by water.
