Longitudinal Section of an Ovary of Pride of Barbados flower
The Longitudinal Section of an Ovary of the Pride of Barbados flower will be one of the Biology Specimens for 2023 WAEC. In the Pride of Barbados flower (Caesalpinia pulcherrima), the ovary is located at the base of the flower, just above the stem. The female reproductive organ contains the ovules, which will eventually develop into seeds if fertilized.

A longitudinal section of the ovary would reveal its internal structure. When you cut the ovary lengthwise, you will see several distinct parts:
- Ovary Wall: The outermost layer of the ovary is called the ovary wall or pericarp. It is typically thick and protective, enclosing the other internal structures.
- Ovules: Inside the ovary, you would find multiple ovules. Small structures are attached to the ovary wall, usually arranged in a radial pattern. Each ovule can develop into a seed if it is fertilized.
- Placenta: The ovules are attached to the ovary wall by structures called placentas. The placenta provides nutrients and support to the developing ovules.
- Ovarian Stigma: At the top of the ovary, you might observe a structure known as the ovarian stigma. It is a receptive surface that collects pollen during pollination.

It’s worth noting that the exact details of the ovary’s longitudinal section can vary depending on the Pride of Barbados flower species or the specific stage of development. Visual references, such as botanical illustrations or images, would provide a more accurate representation of the ovary’s structure.
