The correct Answer is:
To solve the question about the types of placentation in a unilocular ovary where the ovules develop on the inner wall of the ovary, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Unilocular Ovary**: - A unilocular ovary has only one chamber or locule. This means that all the ovules are contained within a single space. 2. **Identifying Placental Types**: - There are several types of placentation based on the arrangement of ovules within the ovary. The main types include: - Marginal - Axile - Parietal - Free Central - Basal 3. **Analyzing Placentation Types**: - **Marginal Placenta**: Ovules are attached along the margin of the ovary. This type is typically found in legumes. - **Axile Placenta**: Ovules are attached to a central column in a multilocular ovary. This does not apply to unilocular ovaries. - **Parietal Placenta**: In this type, the ovules develop on the inner wall of a unilocular ovary. This is the type we are looking for. - **Free Central Placenta**: Ovules are attached to a central column but in a unilocular structure, this is not applicable. - **Basal Placenta**: A single ovule is attached at the base of the ovary. 4. **Conclusion**: - Since the question specifies that the ovules develop on the inner wall of a unilocular ovary, the correct type of placentation is **Parietal Placenta**. 5. **Examples**: - Examples of plants exhibiting parietal placentation include mustard and argemone. ### Final Answer: The type of placentation in a unilocular ovary where the ovules develop on the inner wall of the ovary is **Parietal Placenta**. ---
