SQA National 5 Biology Practice Exam

The structure that contains a female gamete produced by the ovaries in plants is known as the ovule. The ovule is a key component of the reproductive system in flowering plants, and it is located within the ovary of the flower. When fertilization occurs, the ovule develops into a seed.

The ovary, while related as it houses the ovules, is not the structure that directly contains the female gamete. It serves as the protective chamber. The stigma is the top part of the pistil where pollen lands, and the style is the tube that connects the stigma to the ovary. Neither the stigma nor the style plays a direct role in the production or containment of the female gamete. Thus, identifying the ovule as the correct answer underscores its crucial role in reproduction by directly linking to the female gamete and its further development.
