Hint: This can be said that human life begins with it. This is an immature egg cell that eventually matures throughout the process of ovulation, and becomes an ovum, or egg.
Complete answer:
The follicle or Graafian follicle is a fluid-filled structure in the mammalian ovary within which an ovum develops from a single oocyte, through the process of ovulation. At the stage of sexual maturity, these follicles develop by the release of two hormones; FSH and LH.
Additional Information: -The primary follicle begins to mature with the increase in the mass of the ovum and the surrounding follicular cells, through the first meiotic division and becomes a secondary follicle.
-Then after the second division begins, a Graafian follicle is formed. Each follicle has a single oocyte.
-In each ovarian cycle, about 20 primordial follicles are activated to start maturation. However, normally just one follicle fully matures, and therefore the rest contribute to the endocrine function of the ovary.
-In developed follicles, there are two layers of covering, one of the thecal cells that are stimulated by FSH and the other of granulosa cells stimulated by LH.
-When the mature Graafian follicle ruptures, the granulosa or follicle cells remaining in the ovary forming the corpus luteum, that secretes both estrogen and progesterone.
-If pregnancy occurs, the corpus luteum will continue to function as an endocrine gland for the entire pregnancy.
-Fallopian tubes are the site for egg fertilization, this tube connects the ovaries to the uterus. Fertilization successfully occurs in the fallopian tube when a sperm cell meets an egg cell.
So, the correct answer is ‘A single oocyte’.
Note: -Oocytes are rich in the cytoplasm, containing yolk granules to nourish the cell during the early stages of development
-females are born with 1 to 2 million oocytes for their entire lifetime supply of gametes.
-Hormones responsible for the development of follicles are produced by the pituitary gland, these are follicle-stimulating hormone (FSH) and luteinizing hormone (LH).
