Question

Immediately after implantation, ectoderm, endoderm and the mesoderm of embryo is formed from
A. Trophoblast
B. Cytotrophoblast
C. Embryoblast
D. Syncytiotrophoblast​

Answer 1

Answer:

embroblast, so correct option is c.

Answer 2

The correct response to the given question is option C: Embryoblast.

• The option given here is the cells or group of cells that start dividing after the implantation of the zygote.
• After implantation, embryo formation begins which is followed by differentiation of primary germ layers.
• Ectoderm, endoderm and mesoderm are the germ layers that are formed from embryoblast.
• Embryoblast is the mass of cells that divides inside the blastocyst.
• Germ layers start differentiation from this cell mass.
• Trophoblast forms the outer mass of cells of the blastocyst. Cytotrophopblast and syncytiotrophoblast are the types of trophoblast itself, which further form into the placenta.
• As germ layers of the embryo are formed from embryoblast, it is the correct answer.
