Solution

Development:

  • Fertilisation results in the formation of zygote.
  • The zygote divides and redivides to form a ball of cells called blastocyst.
  • The blastocyst gets implanted on the wall of the uterus and forms the embryo.
  • The embryo obtains all the nourishment and oxygen from the mother’s blood.
  • A structure called placenta present in the uterus supplies all the necessary nutrients to the embryo through the umbilical cord.
  • The development of the foetus takes place for nine months
