This unequal division of the zygote is a putative first step for formation of the apical-basal axis of plants and is a fundamental feature of early embryogenesis and morphogenesis in angiosperms. Web16 divisions would be 2^16; which would be 65,536 cells. That is far too many cells to fit into the size of the original zygote (cleavage happens without an overall change in size during blastulation).
