Dear student, Female reproductive system in humans consists of pair of ovaries, pair of oviducts, uterus & vagina. Ovaries produce female germ cells called ova. This ova travels along fallopian tube and at the same time if mating takes place sperm enters female body through vagina. The process of fusion of male gamete sperm with female gamete ova leads to the formation of zygote, the entire process is known as fertilization. This zygote formed, gets attached in the uterine wall & develops into foetus. The female reproductive system in plants consists of pistil(stigma, style and ovaries). Fertilized egg i.e. zygote further develops into embryo and then a new organism mostly inside the female reproductive system. Puberty age is basically defined as the age at which an individual attains certain level of maturity and is capable of reproduction. Girls achieve puberty at an age of 10 to 14 years while boys achieve puberty at an age of 12 to 16 years. Thanks and regards
