What is the characteristic of amphitropous ovule

Options

A. Body is straight but the embryo sac is curved
B. Body of ovule as well as embryo sac are curved
C. Body of ovule is curved but the embryo sac is straight
D. The funiculus is coiled over the body of ovule.

Answer

To determine the characteristic of an amphitropous ovule, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Structure of Ovules**:
- An ovule is a structure in seed plants that develops into a seed after fertilization. It consists of several parts, including the body of the ovule and the embryo sac.

2. **Defining Amphitropous Ovule**:
- The term "amphitropous" refers to a specific type of ovule orientation and shape. In this case, both the body of the ovule and the embryo sac exhibit a particular curvature.

3. **Observing the Curvature**:
- In amphitropous ovules, the body of the ovule is curved, and importantly, the embryo sac is also curved. This curvature gives the ovule a distinctive shape.

4. **Identifying the Shape**:
- The characteristic shape of an amphitropous ovule is often described as horseshoe-shaped due to the curvature of both the body and the embryo sac.

5. **Conclusion**:
- Therefore, the defining characteristic of an amphitropous ovule is that both the body of the ovule and the embryo sac are curved.

### Final Answer:
The characteristic of an amphitropous ovule is that the body of the ovule as well as the embryo sac are curved.
