Placentation in a syncarpous unilcular ovary where ovules occur in suture is

Options

A. Apical placentation
B. Parital placentation
C. Marginal placentation
D. Superficial placentation

Answer

To solve the question regarding the type of placentation in a syncarpous unilocular ovary where ovules occur in sutures, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Syncarpous Ovary**: This refers to an ovary formed from the fusion of multiple carpels. In this case, the carpels are fused together.
- **Unilocular Ovary**: This indicates that the ovary has only one chamber or locule.

2. **Identify the Types of Placentation**:
- **Epical Placentation**: Placenta is located at the apex of the ovary.
- **Parietal Placentation**: Placenta is attached to the inner wall of the ovary, and ovules are found along the suture lines.
- **Marginal Placentation**: Placenta is located along the margins of the ovary.
- **Superficial Placentation**: Placenta is spread over the entire inner surface of a multilocular ovary.

3. **Analyze the Options**:
- **Epical Placentation**: Not applicable as it does not fit the description of a unilocular ovary.
- **Parietal Placentation**: This fits the description as it occurs in a syncarpous unilocular ovary where ovules are found along the suture.
- **Marginal Placentation**: This does not apply since it is characterized by ovules being attached to the margins, not sutures.
- **Superficial Placentation**: This is also not applicable as it pertains to multilocular ovaries.

4. **Conclusion**:
- Based on the analysis, the correct answer is **Parietal Placentation**. This type of placentation occurs in a syncarpous unilocular ovary where the ovules are attached along the suture lines.

### Final Answer:
**Parietal Placentation**
