- list some differences between spermatogenesis and oogenesis. Better when in the table format.Which of the following are stages in the ovarian cycle? Select all that apply. The primary oocyte completes meiosis I and divides unequally, forming a secondary oocyte and a polar body. The rupture of the main follicle releases a secondary oocyte coated with secreted protein and follicle cells. The oocyte enlarges and secretes a layer of proteins, and the cells around the oocyte divide repeatedly. A A corpus luteum develops from the follicle cells left behind after ovulation, and this structure breaks down if pregnancy does not occur. A fluid-filled cavity begins to form in the follicle's cell layer surrounding the primary oocyte.Use the following information to answer next question. The formation of sperm cells from stem cells is known as spermatogenesis. There are three phases in the process of spermatogenesis. The cells formed after the second meiotic division in meiosis is known as primary spermatocytes secondary spermatocytes O spermatids spermatozoa
- Which sequence shows the correct stages of spermatogenesis? Group of answer choices spermatogonium, primary spermatocyte, secondary spermatocyte, spermatid, sperm spermatogonium, spermatid, primary spermatocyte, secondary spermatocyte, sperm sperm, spermatid, secondary spermatocyte, primary spermatocyte, spermatogonium sperm, spermatid, primary spermatocyte, secondary spermatocyte, spermatogoniumCreate a conclusion about spermatogenesis by using the objectives below. To identify the parts of the male reproductive systems To find the stages of spermatogenesis in cross-sections of the testis of the frog, mouse, and man · To describe the morphological characteristics of frog gametesMatch the structure to its function/description (you can use an answer more than once): 3 1234 Produces estrogens Contains a layer called the myometrium Site of early embryonic development Site where folliculogenesis occurs Produces female gametes Birth canal Usual site of fertilization 4 2
- Describe what happens when the secondary oocyte is fertilized by a sperm. Read the textbook and notes carefully. The process is Not straight forward.Rat Testis sample -Basement membrane / basal lamina (same thing) -Sertoli celland nucleus -Spermatogonia -Spermatocytes (primary or secondary) - Spermatids - Spermatozoa (nuclei and tails) - Blood vessel - Seminiferous tubule - Tubule lumen If the structures listed above are present on your photos, you must label them (if they’re not present, no need to).After learning about the reproductive systems, how would advise a couple with following concern: "If we do not want a baby for next two years, how can we calculate the safe sex period?" She shares that her cycle is regular but not standard 28 days long cycle (so the standard explanation form different sources won't work unless you think critically)! At what time of the female cycle is she most likely to prevent fertilization of her ovulated egg? Consider the fact that her cycle is not 28 days but longer or shorter (you pick). Do males have any time (in their cycle- if any) when their gametes would not be able to fertilize the egg? In other words when can intercourse lead to least chance of pregnancy? Feel free to check with your older friends, doctors, nurses, or anyone who you feel comfortable talking about this.
- There are 6 major events in fertilization. Discuss the process of fertilization or conception, with emphasis on the sperm-egg interaction. Proteins on the sperm plasma membrane bind to ZP3 molecules within the zona pellucida of the egg. Why is this event important? Zona binding triggers the acrosome reaction, in which the sperm plasma membrane fuses with the outer acrosomal membrane, causing exocytosis of acrosomal contents. What is in the "acrosomal content"? Acrosomal enzymes begin to dissolve a hole in the zona pellucida. This enzymatic degradation, accompanied by rapid sperm tail beating, moves the sperm through the zona. Where does the sperm intend to reach?Describe the differences between spermatogenesis and oogenesis by filling out the following chart: Comparison Spermatogenesis Oogenesis Sex Capable of this Process Progenitor Cell involved Location of Process Continuity End Products (list all the final products and their quantity)Use the following information to answer the next question. Meiosis. Chromosome Content of Human Cells During a Series of Events Y Mitosis. Differentiation. (n) U Fertilization.
