Describe the sexual reproduction of female and explain |
| Answer» Female reproductive system: This system includes a pair of ovaries, a pair of oviducts, uterus and ****** opening out through urethra.\xa0Eggs, the female gametes develop inside the ovaries. One mature egg is released by either of the ovaries in a month.Ovaries secrete two hormones namely estrogen and progesterone which bring about secondary sexual characters in females.The egg is carried from the ovary to the uterus through a thin oviduct also known as the fallopian tube.The two oviducts combine and open into an elastic bag-like structureknown as the uterus. The uterus opens into ****** through cervix. The uterus helps in the development of the foetus.Copulation: It is the act in which a male reproductive organ enters the female reproductive tract to discharge the male gametes.Fertilisation: It involves the fusion of male and female gametes to give rise to a single cell – zygote. Fertilisation can be external fertilisation or internal fertilisation.Zygote: It is the super cellformed by the fusion of pronuclei of male and female gametes. It divides repeatedly to form an embryo. Embryo gets implanted in the lining of the uterus for further development. | |
