AP PSYCHOLOGY

Detailed explanation-1: -The group of cells present in the center of the morula will eventually give rise to the inner cell mass and the embryo proper. [3] The cells at the periphery, the outer cell mass cells, are critical in the cavitation of the morula that occurs as it transitions into a blastocyst.

Detailed explanation-2: -A blastocyst is made up of an inner group of cells with an outer shell. The inner group of cells will become the embryo. The embryo is what will develop into your baby. The outer group of cells will become structures, called membranes, which nourish and protect the embryo.

Detailed explanation-3: -The inner cell mass of blastocysts is the source of embryonic stem cells, which are broadly applicable in stem cell therapies including cell repair, replacement and regeneration.

Detailed explanation-4: -Answer and Explanation: The answer is (b) Inner cell mass. The inner cell mass cells eventually become what is known as embryonic stem cells; these later become the embryo’s body.

Detailed explanation-5: -The human blastocyst possesses an inner cell mass (ICM), or embryoblast, which subsequently forms the embryo, and an outer layer of cells, or trophoblast, which later forms the placenta.
