Selaginella multiplies vegetatively through

Options

A. Tubers
B. Resting buds
C. Fragmentation
D. All the above.

Answer

**Step-by-Step Solution:**

1. **Understanding Selaginella**:
- Selaginella is a genus of plants classified under the group of pteridophytes, which are seedless vascular plants.

2. **Definition of Vegetative Propagation**:
- Vegetative propagation is a type of asexual reproduction where new plants are formed from parts of the parent plant without the involvement of gametes (sperm and egg).

3. **Identifying Methods of Vegetative Propagation**:
- The question asks about the methods through which Selaginella multiplies vegetatively. The options provided are:
- Tubers
- Resting buds
- Fragmentation
- All of the above

4. **Analyzing Each Option**:
- **Tubers**: These are swollen underground stems that store nutrients and can give rise to new plants. Selaginella can use tubers for vegetative propagation.
- **Resting Buds**: These are structures that allow the plant to survive unfavorable conditions and can develop into new plants. Selaginella can also form resting buds for propagation.
- **Fragmentation**: This occurs when the plant body breaks into pieces, and each piece can grow into a new plant. Selaginella can reproduce through fragmentation as well.

5. **Conclusion**:
- Since Selaginella can multiply through all the mentioned methods (tubers, resting buds, and fragmentation), the correct answer is "all of the above".

**Final Answer**: Selaginella multiplies vegetatively through **all of the above** (tubers, resting buds, and fragmentation).
