In Brassicaceae ovary becomes bilocular due to formation of false septum

Options

A. Diaphragm
B. Replum
C. Annulus
D. Operculum.

Answer

### Step-by-Step Solution:

1. **Understanding the Brassicaceae Family**:
- The Brassicaceae family, commonly known as the mustard family, includes plants like cabbage, broccoli, and mustard. It is characterized by specific floral structures.

2. **Ovary Structure**:
- In Brassicaceae, the ovary is generally described as unilocular, meaning it has one chamber. However, it can also be classified as bicarbular or tricarbular in some instances.

3. **Formation of False Septum**:
- A false septum, also known as a replum, can form within the ovary. This structure does not divide the ovary completely but rather creates a partition.

4. **Impact of the False Septum**:
- The presence of a false septum (replum) divides the unilocular ovary into two halves, effectively making it appear bilocular. This means that although the ovary starts as a single chamber, the formation of the replum gives the appearance of two separate compartments.

5. **Conclusion**:
- Therefore, the statement that in Brassicaceae, the ovary becomes bilocular due to the formation of a false septum is correct. The replum serves as this false septum, dividing the ovary into two sections.
