These processes take place in the seminiferous tubules (ST) of the testis, which are small tubular structures considered the functional units of the testes. Describe the process of mitosis and meiosis. Explain each in detail. a) Describe the regulation of spermatogenesis. b) Describe the endocrine events associated with fertilization of an ovum and its early development. Describe the process of zygote formation. What are the procedures involved during human reproduction? Explain in detail. Q:-With a neat diagram explain the 7-celled, 8-nucleate nature of the female gametophyte. Q:-What is DNA fingerprinting? Mention its application. Q:-What is oogenesis? Give a brief account of oogenesis. Q:-Describe the structure of a seminiferous tubule. Q:-What is triple fusion? Where and how does it take place? Two parents are needed in sexual reproduction close sexual reproduction The formation of a new organism by combining the genetic material of two organisms..During this process the nuclei of the Spermatogenesis. The process by which a haploid sperm cell develops from a germ cell is known as spermatogenesis. This process takes place in the seminiferous tubules of the testes of a male organism. The process starts from the spermatogonial cells which are present near the basement membrane of the seminiferous tubules. Spermatogenesis refers to the synthesis of male gametes that are sperms. It is a process that takes place in male species of an organism. It is the primary and significant process. Definition- It is the process of the formation of haploid, microscopic functional male gametes, spermatozoa from the diploid reproductive cells, spermatogonia. Spermatogenesis leads to the formation of sperms, whereas, oogenesis helps in the formation of ova. The fertilization of sperm and ova leads to the formation of a zygote which further develops into an embryo. The production of sperms from spermatogonia is known as spermatogenesis. The production of eggs from oogonia is known as oogenesis. The temperature in human testis is 2-3 degrees C less than that of body providing a suitable environment for sperm production. Pampiniform plexus play a major role in this. Authors question the full function of Pampiniform plexus; if it is sufficiently efficient to maintain the optimal temperature, … Gametogenesis occurs when a haploid cell (n) is formed from a diploid cell (2n) through meiosis. We call gametogenesis in the male spermatogenesis and it produces spermatozoa. In the female, we call it oogenesis. It results in the formation of ova. This article covers both oogenesis and spermatogenesis. Spermatogenesis produces four haploid cells from one original cell. Spermatogenesis is the process by which sperm cells are produced in the male testes. Hence option D is correct. It is a complex process that involves the division of a single diploid cell into four haploid cells. The first step in spermatogenesis is called meiosis. 4UodH.
