Answer
Soln:
- Fertilisation is defined as the process in which there is a fusion of male gamete and female gamete.
- The male gametes or sperms are released from the male reproductive organ called the penis.
- The sperms release and enter the female body through the vagina.
- From the vagina, sperms travel through the fallopian tubes, where they meet the eggs.
- From there on, the process of fertilisation takes place in the fallopian tube.
- The male gamete cell (sperm) and female gamete cell (egg) fuse together to form a zygote.
- The zygote divides rapidly to form a group of cells called a morula, which becomes the embryo after approximately five days. The foetus is present for about eight weeks after fertilisation.
