Answer:
Oogenesis is the process of egg production in female mammals. It involves the formation of the primary oocyte, which then develops into the mature egg cell or oocyte. During the process of oogenesis, the primary oocyte undergoes two successive mitoses to form the mature oocyte. This process then proceeds through several stages of development until the mature egg cell is ready for fertilization.
With this in mind, let’s take a look at the following statement concerning oogenesis:
Statement 1: Oogenesis takes place in the corpus luteum of the ovary
This statement is TRUE. Oogenesis is a process that takes place in the corpus luteum of the ovary. The corpus luteum is a structure that is formed after a follicle has broken open and released its contents. It produces progesterone, which helps prepare the uterus for the implantation of the embryo. The corpus luteum also contributes to the formation of the zona pellucida, a layer of glycoproteins that encases the mature egg cell and is important for establishing the oocyte–zygote connection during fertilization.
Statement 2: Oogenesis occurs in the interstitial cells of the ovary
This statement is FALSE. Oogenesis does not occur in the interstitial cells of the ovary. Instead, these cells are involved in the production of androgens, which are hormones that help to regulate the reproductive system. They are located adjacent to the follicles and are thought to play a role in the development of the follicle and the regulation of hormone levels in the body.
Statement 3: During oogenesis, the primary oocyte undergoes meiosis
This statement is TRUE. During oogenesis, the primary oocyte undergoes meiosis, a type of cell division that reduces the amount of genetic material in the cell by half. This process begins at puberty and is completed at ovulation. Meiosis I occurs on the day of ovulation and reduces the number of chromosomes in the cell from 46 to 23. Meiosis II occurs a few hours later and reduces the number of chromosomes to the haploid number of 22.
In summary, the statement “Which of the following statements concerning oogenesis is false?” is Statement 2, which is “Oogenesis occurs in the interstitial cells of the ovary.”
