Document Summary

The process of the zygote turning into an embryo, then into a fetus; Reproductive cells (the egg and the sperm, still separated) They each contain only half the chromosomes (23) that are present in all the other cells in the body. That"s how we get 46 in total, we get 23 chromosomes from the father and 23 chromosomes from the mother. When the egg from the mother and the sperm from the father combine. Cell division occurs where the parent cell divides into 2 or more daughter cells and so on, causing the proliferation of the cells. Cell migration: the cells migrate from their point of origin to the specific locations in the embryo. Cell differentiation: the embryo"s unspecialized stem cells into roughly. These stem cells transform by the genes in the cells (epigenetics) and the locations of the cells (environment) Apoptosis: the selective death of certain cells.
