Answer:

The development of the placenta begins during implantation of the blastocyst. The 32-64 cell blastocyst contains two distinct differentiated embryonic cell types: the outer trophoblast cells and the inner cell mass. The trophoblast cells form the placenta. The inner cell mass forms the foetus and foetal membranes
