Is there specifically something we need to know about the 2 cell, 4 cell and 8 cell, 16 cell stages of cell?? I mean morula, blastula and gastrula neural makes sense.. how do we catagorize the 2-4-6-8-16??
The only 2 things you need to know about it is:
1) Its during Cleavage
2) The cells get smaller because with each cleavage you are getting more cells using the same amount cytoplasm.
And i believe the cells are still undifferentiated.
