Vegetative reproduction in Cycas occurs by

Options

A. Scale leaves
B. Sporophylls
C. Bulbils
D. Fragmentation.

Answer

**Step-by-Step Solution:**

1. **Identify the Organism**: The question refers to Cycas, which is a genus of gymnosperms belonging to the family Cycadaceae.

2. **Understand the Types of Reproduction**: Cycas can reproduce both sexually and vegetatively. Sexual reproduction occurs through cones (male and female), while vegetative reproduction involves other methods.

3. **Focus on Vegetative Reproduction**: The question specifically asks about vegetative reproduction in Cycas.

4. **Identify the Method of Vegetative Reproduction**: In Cycas, vegetative reproduction occurs primarily through the formation of bulbils.

5. **Define Bulbils**: Bulbils are fleshy buds that arise adventitiously, meaning they develop in unusual locations, such as in the crevices among persistent leaf bases.

6. **Process of Vegetative Reproduction**: When these bulbils detach from the parent plant, they can grow into a new individual plant, thus facilitating vegetative reproduction.

7. **Eliminate Other Options**: Other methods mentioned, such as scale leaves or sporophylls, do not contribute to vegetative reproduction in Cycas. Therefore, they are not correct.

8. **Conclude the Answer**: The correct answer to the question is that vegetative reproduction in Cycas occurs by bulbils.

**Final Answer**: Vegetative reproduction in Cycas occurs by bulbils.
