Select the incorrect statement about megaspore mother cell.

Options

A. It undergoes mitotic division
B. It undergoes meiotic division.
C. It is a large cell containing dense
D. Generally, a single functional megaspore is produced from it.

Answer

To solve the question regarding the incorrect statement about the megaspore mother cell, we will analyze each option provided in the context of megasporogenesis, the process of forming megaspores from the megaspore mother cell.

### Step-by-Step Solution:

1. **Understanding Megaspore Mother Cell (MMC)**:
- The megaspore mother cell is a large cell located within the ovule of seed plants. It is responsible for producing megaspores through a specific process.

2. **Identifying the Process of Megasporogenesis**:
- Megasporogenesis is the process through which the megaspore mother cell undergoes division to form megaspores. This process is crucial for the development of the female gametophyte.

3. **Analyzing the Statements**:
- **Statement 1**: "It undergoes mitotic division."
- This statement is incorrect. The megaspore mother cell undergoes meiotic division, not mitotic division.
- **Statement 2**: "It undergoes meiotic division."
- This statement is correct. The megaspore mother cell indeed undergoes meiotic division to produce megaspores.
- **Statement 3**: "It is a large cell containing dense cytoplasm."
- This statement is also correct. The megaspore mother cell is characterized by its large size and dense cytoplasm.
- **Statement 4**: "Generally, a single functional megaspore is produced from it."
- This statement is correct as well. Typically, from the four megaspores produced, only one is functional while the others degenerate.

4. **Conclusion**:
- The incorrect statement about the megaspore mother cell is the first one: "It undergoes mitotic division." Therefore, this is the answer to the question.

### Final Answer:
The incorrect statement about the megaspore mother cell is: **"It undergoes mitotic division."**
