Options

A. 2
B. 3
C. 1
D. 4

Answer

To answer the question "A single ovule produces how many female gametes?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Ovule**: The ovule is a structure in seed plants that develops into a seed after fertilization. It contains the female gametes.

2. **Identifying the Megaspore Mother Cell (MMC)**: The ovule contains a cell known as the Megaspore Mother Cell (MMC), which is diploid (2N). This cell is responsible for producing female gametes.

3. **Meiosis Process**: The Megaspore Mother Cell undergoes meiosis, which is a type of cell division that reduces the chromosome number by half. During the first meiotic division, the MMC divides to form two haploid cells (N).

4. **Second Meiosis Division**: These two haploid cells then undergo a second meiotic division, resulting in a total of four haploid cells.

5. **Degeneration of Cells**: Out of these four haploid cells produced, typically three cells degenerate and only one cell survives.

6. **Formation of the Embryo Sac**: The surviving cell develops into the embryo sac, which contains the female gamete.

7. **Conclusion**: Therefore, a single ovule ultimately produces only one female gamete.

### Final Answer:
A single ovule produces **1 female gamete**.
