The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Angiospermic Ovule**: - Angiosperms are flowering plants, and their ovules are crucial for reproduction. The ovule is the structure that develops into a seed after fertilization. 2. **Structure of the Ovule**: - A typical angiospermic ovule consists of several key components: - **Integument**: The outer protective layer. - **Micropyle**: The opening at one end of the ovule. - **Chalaza**: The opposite end of the micropyle. - **Funiculus**: The stalk that attaches the ovule to the ovary wall. 3. **Embryo Sac Composition**: - Inside the ovule, there is an embryo sac which contains: - **Antipodal Cells**: Typically three cells located at the chalazal end. - **Polar Nuclei**: Two nuclei located in the center of the embryo sac. - **Synergids**: Two cells located near the micropyle, assisting in fertilization. - **Egg Cell**: One cell located adjacent to the synergids. 4. **Shape and Orientation**: - The ovule is often described as being 180 degrees turned, meaning that its body is oriented in a specific way that is not horseshoe-shaped. The body of the ovule is curved but not in a horseshoe shape. 5. **Evaluating Options**: - **Option 1**: "Body is curved like Horseshoe" - This is incorrect. - **Option 2**: "Body rotated by 180 degrees" - This is correct. - **Option 3**: "Both body and embryo sac are curved" - This is incorrect; only the body is curved. - **Option 4**: "Funicle is long and coils around the body" - This is incorrect; the funicle does not coil 360 degrees around the ovule. 6. **Conclusion**: - The correct answer is that the body of the ovule is rotated by 180 degrees, making option B the right choice.
