Ovule Structure and Types
An ovule is the female reproductive structure present in the ovary of a flower. It consists of a megasporangium surrounded by integuments. After fertilization, it develops into a seed.
There are four types of ovule based on their orientation and position in the ovary:
1. Anatropous: The ovule is inverted and hangs from the top of the ovary. The funiculus attaches to the chalaza, and the micropyle is located at the bottom.
2. Campylotropous: The ovule is curved, and the funiculus attaches to the side of the ovule. The micropyle is located at the top.
3. Amphitropous: The ovule is partly inverted and partly erect. The funiculus attaches to the middle of the ovule, and the micropyle is located at the top.
4. Circinotropous: The ovule is coiled, and the funiculus attaches to the side of the ovule. The micropyle is located at the top.
Answer Explanation
In the given question, the description matches with the amphitropous type of ovule. The embryo sac becomes horseshoe-shaped, which is a characteristic of the amphitropous ovule. Additionally, the funiculus and micropyle are close to each other, which is also a feature of the amphitropous ovule. Therefore, the correct answer is option A (Amphitropous).
