what is the difference between morula and blastocyst
Morula A morula is distinct from a blastocyst in that a morula (3–4 days post fertilization) is a 16-cell mass in a spherical shape whereas a blastocyst (4–5 days post fertilization) has a cavity inside the zona pellucida along with an inner cell mass.
