Both haploid cells containing half of the needed information to make a new human being, their combo forms a diploid cell. This new cell, called a zygote, has all the material needed to form a human—half from the mother and half from the father.]]> 2019-04-23 02:41:33 UTC https://padlet.com/waisj1/jzy5pjrh3p74/wish/353228919 waisj1 https://padlet.com/waisj1/jzy5pjrh3p74/wish/353229722 After zygote is formed it undergoes rapid cell division to form the blastula which will form the blastocyst. The rapid, many rounds of cell division are called cleavage. When the zygote has split into 16 cells its now the Morula. When zygote is finished dividing, Blastocyst forms in preparation for implantation.]]> 2019-04-23 02:47:02 UTC https://padlet.com/waisj1/jzy5pjrh3p74/wish/353229722 waisj1 https://padlet.com/waisj1/jzy5pjrh3p74/wish/353234163 2019-04-23 03:18:51 UTC https://padlet.com/waisj1/jzy5pjrh3p74/wish/353234163 waisj1 https://padlet.com/waisj1/jzy5pjrh3p74/wish/353234365 Outermost membrane of blastocyst (Trophoblast) and surrounds embryo, allantois is explained later.]]> 2019-04-23 03:20:23 UTC https://padlet.com/waisj1/jzy5pjrh3p74/wish/353234365 waisj1 https://padlet.com/waisj1/jzy5pjrh3p74/wish/353236162 forms within the blastocyst, eventually the embryo.]]> 2019-04-23 03:34:55 UTC https://padlet.com/waisj1/jzy5pjrh3p74/wish/353236162 waisj1 https://padlet.com/waisj1/jzy5pjrh3p74/wish/353237557 secreted by trophoblast during implantation..
