Question

mention one main function of blastocyst after fertilization​

Answer 1

Answer:

The blastocyst consists of cells forming an outer trophectoderm (TE, trophoblast) layer, an inner cell mass (ICM, embryo blast) and a blastocoel (fluid-filled cavity). The inner cell mass will form the entire embryo, and is the source of true embryonic stem cells capable of forming all cell types within the embryo.
