Ovary is one-chambered but it becomes two-chambered due to the formation of false septum in

Options

A. Brassica
B. Pisum
C. Hibiscus
D. Dianthus

Explanation

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about an ovary that is initially one-chambered but becomes two-chambered due to the formation of a false septum.

2. **Definition of False Septum**: A false septum is a thin membrane or partition that separates two chambers within an ovary. It is important to note that this structure does not divide the ovary into two distinct parts but rather creates the appearance of two chambers.

3. **Identifying the Plants**: The plants mentioned in the video transcript that exhibit this characteristic include Brassica, Prism, Hibiscus, and Dianthus.

4. **Specific Characteristics of Brassica**: The Brassica plant, which belongs to the family Brassicaceae, has a unilocular (one-chambered) ovary that becomes bilocular (two-chambered) due to the development of the false septum.

5. **Terminology**: The false septum in Brassica is referred to as the "replum." This structure is crucial for understanding the ovary's development and its placentation type, which is parietal in this case.

6. **Conclusion**: Therefore, the correct answer to the question is that the ovary becomes two-chambered due to the formation of a false septum in **Brassica**.

### Final Answer:
The ovary is one-chambered but becomes two-chambered due to the formation of a false septum in **Brassica**.
