Quizplus · Accepted Answer

This is because a primordial follicle consists of a primary oocyte surrounded by a single layer of squamous granulosa cells. Once the primordial follicle begins to grow, it becomes a secondary follicle which has more layers of granulosa cells. As the follicle continues to develop, it becomes a mature or graafian follicle, which contains a fluid-filled space called the antrum and a fully grown secondary oocyte. The corpus luteum is formed after ovulation when the follicle collapses and transforms into a temporary endocrine gland.
