During early cleavage stages in drosophila, nuclei divide through 13 cycles in the absence of any cytoplasmic cleavage. This division creates an embryo of many nuclei contained within one shared cytoplasm surrounded by one common plasma membrane, this process is called as-

after the 8-cell stage, the mammalian embryo develops an outer layer (which becomes the fetal portion of the placenta), and an inner cell mass that generates all the cells of embryo. The cells of the inner cell mass are thus said to be-
