Question

Name the stage of human embryo at which it gets implanted. Explain the process of implantation.

OR

Draw a labelled diagram of a human blastocyst. How does it get implanted in the uterus ?

Answer 1

The human embryo gets implanted at blastocyst. 

The trophoblast layer of the blastocyst get attached to the endometrium and the inner cell mass gets differentiated as the embryo. After attachment the uterine cell divides rapidly and covers the blastocyst. As a result the blastocyst becomes embedded in the endometrium of the uterus.
