Answer:

Cleavage: rapid, multiple rounds of mitotic cell division where the overall size of the embryo does not increase. The developing embryo is called a blastula following completion of cleavage. Gastrulation: the dramatic rearrangement (movement) of cells in the blastula to create the embryonic tissue layers.
