Cells Move to New Positions as an Embryo Establishes Its

Question

Cells move to new positions as an embryo establishes its three germ tissue layers during
A)determination.
B)cleavage.
C)fertilization.
D)induction.
E)gastrulation.

Accepted Answer

Gastrulation is the process during which the embryo forms the three germ tissue layers, called endoderm, mesoderm, and ectoderm. This process involves a dramatic reorganization of cells, including migration to new positions to establish the correct layering. The other choices do not directly involve the movement of cells during germ layer formation.
