A Human Gastrula Is Composed of Three Cell Layers Stacked

question 78

True/False

A human gastrula is composed of three cell layers stacked on top of one another (like the layers of a sandwich). As the early cells within human embryos are incapable of migration, this tri-laminar disc is the result of mitotic cell division and not the active movement of cells.
