Learn about the Reproductive System
The female reproductive system has two functions: The first is to produce egg cells, and the second is to protect and nourish the offspring until birth. The male reproductive system has one function, and it is to produce and deposit sperm.
SPERMATOGENESIS.....(That's a big word!)
Spermatogenesis is the process of the production of sperms from the immature germ cells in males. It takes place in seminiferous tubules present inside the testes. During spermatogenesis, a diploid spermatogonium (male germ cell) increases its size to form a diploid primary spermatocyte. This diploid primary spermatocyte undergoes first meiotic division (meiosis I), which is a reductional division to form two equal haploid secondary spermatocytes. Each secondary spermatocyte then undergoes second meiotic division (meiosis II) to form two equal haploid spermatids. Hence, a diploid spermatogonium produces four haploid spermatids. These spermatids are transformed into spermatozoa (sperm) by the process called spermiogenesis.
Oogenesis...(okay is this word even in the dictionary??)
Oogenesis is a type of gametogenesis. It is the process of producing female gametes, once sex determination of the embryo has occurred. The presence of the SRY gene on the Y chromosome leads to male gonad formation and spermatogenesis, while female gonad development is the ‘default state’. The process of oogenesis creates egg cells, known as ova, and is completed throughout a woman’s lifetime. Like spermatogenesis, oogenesis involves the creation of haploid sex cells through the process of meiosis.(MIND BLOWN)
