Solution:
An embryo with about 64-cells and a cavity called blastocoel is known as blastocyst. It is composed of an outer envelope of cells the trophoblast. Implantation is attachment of blastocyst to the uterine wall. This occurs 7-days after fertilization. It develops from 8-celled morula to 16-celled morula and then 64-celled stage. The blastocyst sinks into a pit formed in the endometrium and gets completely burried in the endometrium.
