In plants, the term embryogenesis covers development from the time of fertilization until dormancy occurs the basic body plan of the sporophyte is established during embryogenesis however, this plan is reiterated and elaborated after dormancy is broken. Implantation of blastocyst the final stage of early embryo development is the implantation of the blastocyst into the endometrial lining of the uterus. Embryonic development are the stages of maturation of a zygote (fertilized egg).
Stage 1 embryos have the potential to develop into all of the subsequent stages of a human beingstage 1 starts at the beginning of fertilization, when an oocyte is penetrated by a sperm, and ends with the intermingling of the paternal (male) and maternal (female) chromosomes on the spindle at metaphase of the first mitotic division of the single cell.
