For example, for mammals, the process would begin with zygote formation and end with birth. For insects, the process would begin at zygote formation and end with larval hatching. For plant zygotic embryos, this would be from zygote formation to the end of seed dormancy. For plant vegetative embryos, this would be from the initial determination of the cell or group of cells to form an embryo until the point when the embryo becomes independent of the parent plant. developing organism embryonic organism MAT:0000226 BSA:0000039 FMA:69068 http://neurolex.org/wiki/Category:Embryonic_organism CALOHA:TS-0229 VHOG:0001766 developmental tissue AEO:0000169 BTO:0000379 MIAA:0000019 UBERON:0000922 UMLS:C0013935 EHDAA:38 Obsoleted in ZFA.
