Type of divisions that occurs during formation of megaspore is

Options

A. Meiosis
B. Mitosis
C. Meiosis followed by mitosis
D. Mitosis followed by meiosis.

Answer

To determine the type of division that occurs during the formation of megaspores, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Source of Megaspores**:
- Megaspores are formed from a specialized cell known as the Megaspore Mother Cell (MMC).

2. **Understand the Nature of the Megaspore Mother Cell**:
- The Megaspore Mother Cell is diploid (2n), meaning it contains two sets of chromosomes.

3. **Determine the Type of Division**:
- The Megaspore Mother Cell undergoes meiosis, which is a type of cell division that reduces the chromosome number by half, resulting in haploid cells.

4. **Outcome of Meiosis**:
- During meiosis, the MMC divides to produce four haploid megaspores.

5. **Functional and Degenerative Megaspores**:
- Out of the four megaspores formed, three typically degenerate, leaving one functional megaspore.

6. **Conclusion**:
- Since the formation of megaspores involves meiosis, the correct answer to the question is that the type of division that occurs during the formation of megaspores is **meiosis**.

### Final Answer:
The type of division that occurs during the formation of megaspore is **meiosis**.
