Question

The fertilized egg develops into the ______ by repeated division of cells.

Answer 1

1. The mature ovum is released from the ovary into the Fallopian tube. When sperms are released into the female reproductive system, they move towards the ovum and one of the sperms fuses with the egg. This fusion is called fertilization.
2. Fertilization takes place in the Fallopian tube. The fertilized egg is called the zygote.
3. After fertilization, the zygote moves into the uterus and fixes itself to the inner wall of the uterus. This is known as implantation.
4. The fertilized egg develops into the embryo by repeated division of the cells. This leads to the formation of different parts, and the embryo then turns into a foetus.

Final answer: The fertilized egg develops into the embryo by repeated division of cells.
