Cycas reproduces vegetatively by

Options

A. sporophylis
B. bulbils
C. fragmentation
D. rhizome

Answer

To answer the question "Cycas reproduces vegetatively by," we need to analyze the options provided and understand the vegetative reproduction methods of Cycas.

### Step-by-Step Solution:

1. **Understanding Cycas**:
- Cycas is a genus of gymnosperms, which are seed-producing plants that do not form flowers or fruits.

2. **Types of Reproduction**:
- Cycas can reproduce both sexually and vegetatively.
- Vegetative reproduction is a form of asexual reproduction where new plants grow from parts of the parent plant.

3. **Identifying Vegetative Methods**:
- The options given are:
- A) Sporophyll
- B) Bulbils
- C) Fragmentation
- D) Rhizome

4. **Analyzing Each Option**:
- **Sporophyll**: This is a leaf that bears spores. It is involved in sexual reproduction, not vegetative reproduction. Therefore, this option is incorrect.
- **Bulbils**: These are small bulbs that can develop in the crevices of leaf bases. They can separate from the parent plant and grow into new independent plants. This is a correct method of vegetative reproduction for Cycas.
- **Fragmentation**: This refers to the process where a part of the plant breaks off and grows into a new plant. Cycas does not reproduce this way, making this option incorrect.
- **Rhizome**: This is a horizontal underground stem that can give rise to new plants. Cycas does not primarily use rhizomes for reproduction, so this option is also incorrect.

5. **Conclusion**:
- The only correct method of vegetative reproduction in Cycas from the options provided is **Bulbils** (Option B).

### Final Answer:
Cycas reproduces vegetatively by **Bulbils**.
