Assertion: All embryo with 8 to 16 blastomeres is called a morula.
Reason: The morula containues to divide and transforms into trophoblast.

Text Solution

Verified by Experts

The correct Answer is:
C
The embryo with 8 to 16 blastomeres is called a morula. The morula continues to divide and transforms into blastocyst as it moves further into the uterus. The blastomeres in the blastocyst are arranged into an outer layer called trophoblast and an inner group of cells attached to trophoblast called the inner cell mass.
