In blastocyst stage compacted cells and intracellular fluid accumulates to form inner cell mass of blastocyst. The development of embryoblast begins from here. After the completion of 100 cells cleavage, blastula stage is produced by the divisions of morula. The embryo becomes blastula after the successful round of cell divisions.
