Question: during which stage is the embryo 8 cells, and during which stage is it 32 cells? I realize that the morula becomes the blastula which gastrulates to become the gastrula, but I don't know which stage is technically the "8-cell" stage and which is the "32-cell" stage. Thanks!

double check elsewhere because I'm not 100%, but I'm pretty sure 16-32 cells is a morula and anything before that is just an embryo....
