It is a biological process by which diploid or haploid precursor cells undergo cell division and differentiation to form mature haploid gametes.
Depending on the biological life cycle of the organism, gametogenesis occurs by meiotic division of diploid gametocytes into various gametes, or by mitotic division of haploid gametogenous cells. For example, plants produce gametes through mitosis in gametophytes. Animals produce gametes directly through meiosis in organs called gonads (testicle in males and ovary in females). Males and females of a species that reproduces sexually have different forms of gametogenesis. 1  spermatogenesis (male). 2  oogenesis (female). Gametogenesis | Back to Top. Gametogenesis is the process of forming gametes (by definition haploid, n) from diploid cells of the germ line. Spermatogenesis is the process of forming sperm cells by meiosis (in animals, by mitosis in plants) in specialized organs known as gonads (in males these are termed testes). After division the cells undergo differentiation to become sperm cells. Oogenesis is the process of forming an ovum (egg) by meiosis (in animals, by mitosis in the gametophyte in plants) in specialized gonads known as ovaries. Gametogenesis is a process in which an organism makes gametes, cells which are used in sexual reproduction. Each gamete contains half the genetic material of the parent organism. When it fuses with another gamete, it creates a complete set of DNA. Gametogenesis is a process in which an organism makes its sex cells. When one gamete fuses with another, they create a complete set of DNA that serves as a blueprint for that organism. Females produce eggs, or oocytes, in the ovaries during a process known as oogenesis. View slideshow of images above. Gametogenesis: The development and production of the male and female germ cells required to form a new individual. The male and female germ cells are called gametes. The gametes in human males are produced by the testes, two globe-shaped reproductive organs just below the penis. The reproductive organs in both males and females (testes and ovaries, respectively) begin gametogenesis with a primitive germ cell. A primitive germ cell is a seed cell. Like a seed planted in a garden, a primitive germ cell initiates the process that eventually results in a new being. Best Answer: Gametogenesis is the creation of gametes. Depending on the biological life cycle of the organism, gametogenesis occurs by meiotic division of gametocytes into various gametes or by mitotic division of haploid gametogenous cells. For example, plants produce gametes through mitosis in gametophytes. The gametophytes grow from haploid spores after sporic meiosis. Gametogenesis is a process by which diploid or haploid precursor cells undergo cell division and differentiation to form mature haploid gametes. In most animals the ovaries produce the female gametes (ova) and the testicles the male gametes (sperm). it is where the female sex cells are made. The process by which haploid (or diploid in some organisms) precursor gametes become mature gametes. Gametogenesis is the formation of eggs by the female and sperm by the male. Singularly, Oogenisis is the formation of an ovum from a female, and Spermatogenisis is the formati … on of sperm by a male. In most animals the ovaries produce the female gametes (ova) and the testicles the male gametes (sperm). it is where the female sex cells are made. The process by which haploid (or diploid in some organisms) precursor gametes become mature gametes. Gametogenesis. the process of development and formation of the sex cells, or gametes. The gametogenesis of the male gametes (spermatozoids, sperms) is called spermatogenesis; and that of the female gametes (the egg cells), oogenesis. Gametogenesis is a biological process by which diploid or haploid precursor cells undergo cell division and differentiation to form mature haploid gametes. Animals produce gametes directly through meiosis in organs called gonads (testicle in males and ovary in females). Males and females of a species that reproduces sexually have different forms of gametogenesis. 1  spermatogenesis (male). 2  oogenesis (female).
