HRP … WebThe next stage in embryonic development is gastrulation, in which the cells in the blastula rearrange themselves to form three layers of cells and form the body plan. The embryo during this stage is called a gastrula. Gastrulation results in three important outcomes: The formation of the embryonic tissues, called germ layers.
