Q. In which stage does the embryo differentiate into trophoblast and an inner group of cells?

Solution:

The blastocyst is a structure formed in the early development of mammals. It possesses an inner cell mass (ICM) which subsequently forms the embryo. The outer layer of the blastocyst consists of cells collectively called the trophoblast.
