Where does fertilisation take place?

• Fertilisation: The process in which a sperm cell fuses with an egg cell to form a zygote, which eventually develops into an embryo.


• Location: Fertilisation takes place in the Fallopian tube of the female reproductive system.

Explanation:

• The female reproductive system consists of several organs, including the uterus, vagina, fallopian tubes, and cervix.


• During sexual intercourse, sperm is deposited in the vagina.


• The sperm then travels through the cervix and enters the uterus.


• From the uterus, the sperm continues its journey through the Fallopian tube.


• If an egg is present in the Fallopian tube, fertilisation can occur.


• The sperm penetrates the egg, and their genetic material combines to form a zygote.


• The zygote then implants itself in the uterus, where it develops into an embryo.

Conclusion:

• Fertilisation takes place in the Fallopian tube of the female reproductive system.


• It is the process of sperm fusing with an egg to form a zygote.
