Megaspore mother cell differentiates in the:

Options

A. nucellus near chalazal region
B. integuments
C. hilum
D. nucellus near the micropylar region

Answer

To solve the question regarding where the Megaspore mother cell (MMC) differentiates, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Context**: The Megaspore mother cell is a crucial component in the process of gametogenesis in plants, specifically in the formation of female gametes.

2. **Identifying the Location**: The question asks where the Megaspore mother cell differentiates. The options provided include:
- New cellars near chalazal region
- Integuments
- Hilum
- New cellars near the micropillar region

3. **Analyzing Each Option**:
- **New cellars near chalazal region**: This is not the typical location for MMC differentiation.
- **Integuments**: These are protective layers and do not give rise to the MMC.
- **Hilum**: This is the part of the seed where the ovule attaches, but it is not where the MMC differentiates.
- **New cellars near the micropillar region**: This is a specific area where the new cellar cells are located, and it is known that the MMC differentiates here.

4. **Conclusion**: Based on the analysis, the Megaspore mother cell differentiates in the new cellars near the micropillar region.

5. **Final Answer**: The correct answer is **D) New cellars near the micropillar region**.
