The vegetative propagules in aquatic plants like Vallisneria and Eichhornia are

Options

A. Stolon in both
B. Suker and offset respectively
C. Stolon and offset respectively
D. Offset in both

Answer

**Step-by-Step Solution:**

1. **Identify the Aquatic Plants**: The question mentions two specific aquatic plants: Vallisneria and Eichhornia.

2. **Understand Vegetative Propagation**: Vegetative propagation is a form of asexual reproduction where new plants grow from parts of the parent plant, such as stems, leaves, or roots.

3. **Determine the Type of Vegetative Propagule for Vallisneria**:
- Vallisneria reproduces using **stolons**.
- Stolons are horizontal stems that grow along the surface of the soil or substrate, and they can produce new plants at their nodes.

4. **Determine the Type of Vegetative Propagule for Eichhornia**:
- Eichhornia, commonly known as water hyacinth, reproduces using **offsets**.
- Offsets are lateral branches that grow from the main stem and can develop into new plants.

5. **Summarize the Findings**:
- Vallisneria utilizes stolons for vegetative propagation.
- Eichhornia utilizes offsets for vegetative propagation.

6. **Conclusion**: The vegetative propagules in Vallisneria are stolons, while in Eichhornia, they are offsets.

**Final Answer**: The vegetative propagules in aquatic plants like Vallisneria and Eichhornia are stolons and offsets, respectively.
