Vegetative propagation in water hyacinth takes place by

Options

A. A. rhizome
B. B. bulbil
C. C. leaf bud
D. D. offset

Answer

**Step-by-Step Solution:**

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

2. **Identifying the Plant**: The question specifically asks about water hyacinth, which is an aquatic plant known for its rapid growth and ability to cover water bodies.

3. **Types of Vegetative Structures**: In plants, various structures can be involved in vegetative propagation, including rhizomes, bulbs, leaf buds, and offsets.

4. **Evaluating the Options**:
- **A. Rhizome**: This is a horizontal underground stem that can produce new shoots. However, water hyacinth does not primarily propagate through rhizomes.
- **B. Bulbule**: This term refers to small bulbs that can develop into new plants. Water hyacinth does not use bulbules for propagation.
- **C. Leaf Bud**: Leaf buds can give rise to new shoots, but this is not the primary method of propagation for water hyacinth.
- **D. Offset**: This is a small lateral shoot that develops from the parent plant and can grow into a new plant. Water hyacinth primarily propagates through offsets.

5. **Conclusion**: Based on the evaluation of the options, the correct answer is D. Offset, as water hyacinth reproduces vegetatively through this structure.

**Final Answer**: Vegetative propagation in water hyacinth takes place by D. Offset.
