The correct Answer is:
To solve the question regarding the orientation of the ovule in relation to the funicle, we need to analyze the characteristics of the different types of ovules provided in the options. ### Step-by-Step Solution: 1. **Understanding the Ovule Structure**: - The ovule consists of several parts: the micropyle, chalaza, and funicle. The arrangement of these parts helps classify the type of ovule. 2. **Analyzing the Options**: - **Orthotropous**: This is the simplest type of ovule where the micropyle, chalaza, and funicle are in a straight line. This does not match our description since the body is straight but at right angles to the funicle. - **Campylotropous**: In this type, the funiculus is elongated, and the ovule is curved. This does not fit the description either. - **Hemitropous**: Here, the body of the ovule is turned 90 degrees, making the micropyle and chalaza lie in a straight line, while the funicle is at a right angle. This matches the description given in the question. - **Amphitropous**: In this type, the body of the ovule is curved and takes a horseshoe shape, which again does not fit the description provided. 3. **Conclusion**: - Based on the analysis, the correct answer is **Hemitropous** (Option C), as it describes an ovule where the body is straight but oriented at a right angle to the funicle. ### Final Answer: The body of the ovule is straight but at right angles to the funicle; it is **Hemitropous**.
