Options

A. circinotropous
B. anatropous
C. hemitropous
D. amphitropous

Answer

To solve the question regarding the type of ovule in Opuntia that is coiled and turned at more than 360 degrees, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Structure of Ovule**:
- The ovule is a crucial part of the plant reproductive system, containing the female gamete (ovum) within the embryo sac.

2. **Identifying Types of Ovules**:
- There are different types of ovules based on their orientation and the angle of curvature. Common types include:
- **Atropous**: The ovule is straight, with the micropyle at one end.
- **Anatropous**: The ovule is turned 180 degrees, bringing the micropyle closer to the funiculus.

3. **Analyzing the Question**:
- The question specifies that the ovule of Opuntia is coiled and turned at more than 360 degrees. This indicates that the ovule has undergone a complete turn and then some.

4. **Determining the Correct Type**:
- If the ovule turns 360 degrees, it returns to its original position, similar to the Atropous type. However, since it is specified that it turns more than 360 degrees, this indicates a specific type of ovule.
- The type of ovule that is coiled and turned at more than 360 degrees is referred to as **Circinotropus**.

5. **Conclusion**:
- Therefore, the correct answer to the question is that the ovule of Opuntia is classified as **Circinotropus**.

### Final Answer:
The ovule of Opuntia is Circinotropus.
