When ovule turns at an angle of `360^(@)`, so that funicle becomes coiled around the ovule, such types of ovules are regarded as

Options

A. Amphitropous
B. Circinotropous
C. Campylotropous
D. Anatropous

Answer

To solve the question regarding the type of ovule that turns at an angle of 360 degrees, resulting in the funicle coiling around the ovule, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Ovule Types**: Begin by familiarizing yourself with the different types of ovules. The main types are Orthotropous, Anatropous, Campylotropous, Amphitropous, and Circinotropous.

2. **Identify Circinotropous Ovule**: Recognize that a Circinotropous ovule originates as an Orthotropous ovule, where the chalaza, micropyle, and funicle are aligned in a straight line.

3. **Growth Process**: Understand that in Circinotropous ovules, there is unilateral growth of the funicle. This growth leads to the funicle coiling around the ovule.

4. **Complete Rotation**: Note that the Circinotropous ovule undergoes a complete rotation (360 degrees), which causes the funicle to completely surround the ovule.

5. **Examples**: Identify examples of plants that have Circinotropous ovules, such as Opuntia.

6. **Conclusion**: Based on the above understanding, conclude that when an ovule turns at an angle of 360 degrees and the funicle coils around it, it is classified as a Circinotropous ovule.

### Final Answer:
The type of ovule that turns at an angle of 360 degrees, causing the funicle to coil around it, is called a **Circinotropous ovule**.
