The Ovary in Flowers

The ovary is a crucial part of a flower's reproductive system. It is the female reproductive organ that contains the ovules, which eventually develop into seeds after fertilization. The position of the ovary in a flower can vary, and it can be inferior, superior, or half inferior.

Flowers with an Inferior Ovary
In flowers with an inferior ovary, the ovary is located below the attachment point of the other floral parts such as the petals, sepals, and stamens. This means that when these parts are attached to the receptacle, the ovary is positioned beneath them.

Flowers with a Half Inferior Ovary
In flowers with a half inferior ovary, the ovary is partially below and partially above the attachment point of the other floral parts. This means that the lower part of the ovary is below the attachment point, while the upper part extends above it.

The Correct Answer: Peach (Option A)
In the given options, the correct answer is option A, peach. Peach flowers have a half inferior ovary. The ovary of a peach flower is partially below the attachment point of the other floral parts, such as the petals and stamens. The lower part of the ovary is inferior, while the upper part is superior.

Incorrect Options:
- Option B, cucumber: Cucumber flowers have a superior ovary, not a half inferior ovary.
- Option C, cotton: Cotton flowers also have a superior ovary, not a half inferior ovary.
- Option D, guava: Guava flowers have a superior ovary, not a half inferior ovary.

Conclusion
In conclusion, the correct answer to the question is option A, peach. Peach flowers have a half inferior ovary, with the lower part of the ovary positioned below the attachment point of the other floral parts and the upper part extending above it.
