D) morula

Question

Quizplus · Accepted Answer

The blastocoele is a fluid-filled cavity that forms within the blastocyst, which is an early stage of embryonic development. The blastocoele is surrounded by the trophoblast, which is the outer layer of cells of the blastocyst. The inner cell mass is located within the blastocoele and will eventually give rise to the embryo. The morula is an earlier stage of embryonic development than the blastocyst, and does not have a fluid-filled cavity.
