An ovule which becomes curved so that the nucellus and embryo sac lie ...
In campylotropous ovule, the body is curved but the embryo sac is straight eg. Capsella. In Anatropous, the body of ovule is inverted and gets fused with funiculus along its whole length on one side (most of the angiosperms). In orthotropous condition the body of ovule lies straight and upright over the funicle. e.g. Piperaceae, Polygonaceae.

An ovule which becomes curved so that the nucellus and embryo sac lie ...
Explanation:
1. Hemitropous:
- In a hemitropous ovule, the ovule becomes curved so that the nucellus and embryo sac lie at right angles to the funicle.
- This type of ovule is commonly found in members of the family Compositae (Asteraceae).
- The ovule is bent in such a way that the micropyle and chalaza come close to each other.
- The nucellus and the embryo sac are positioned at a right angle to the funicle.
- This type of ovule is considered to be intermediate between anatropous and campylotropous ovules.
2. Campylotropous:
- In a campylotropous ovule, the ovule is curved so that the micropyle and chalaza are near each other.
- The ovule is twisted, and the funicle is curved.
- The nucellus and embryo sac are positioned at right angles to the funicle.
- This type of ovule is found in some members of the family Cucurbitaceae.
3. Anatropous:
- In an anatropous ovule, the ovule is completely inverted, with the micropyle and chalaza at opposite ends.
- The ovule is straight, and the nucellus and embryo sac are positioned parallel to the funicle.
- This type of ovule is commonly found in many flowering plants.
Conclusion:
- In the given scenario, where the ovule becomes curved so that the nucellus and embryo sac lie at right angles to the funicle, the correct term to describe this type of ovule is hemitropous.

2. Campylotropous:
- In a campylotropous ovule, the ovule is curved so that the micropyle and chalaza are near each other.
- The ovule is twisted, and the funicle is curved.
- The nucellus and embryo sac are positioned at right angles to the funicle.
- This type of ovule is found in some members of the family Cucurbitaceae.
3. Anatropous:
- In an anatropous ovule, the ovule is completely inverted, with the micropyle and chalaza at opposite ends.

- This type of ovule is commonly found in many flowering plants.
Conclusion:
- In the given scenario, where the ovule becomes curved so that the nucellus and embryo sac lie at right angles to the funicle, the correct term to describe this type of ovule is hemitropous.
