Question

What is the function of trophoblast and inner cell mass?

Answer 1

EXPLANATION

Trophoblast

Trophoblasts are cells forming the outer layer of a blastocyst, which provide nutrients to the embryo and develop into a large part of the placenta.

Inner cell mass ( ICM )

In early embryogenesis of most eutherian mammals, the inner cell mass (abbreviated ICM and also known as the embryoblast in mammals or pluriblast) is the mass of cells inside the primordial embryo that will eventually give rise to the definitive structures of the fetus.
