To examine: Whether the statement “Because of the many later developmental transformations that produce the elaborately structured organs, the body plan set up during gastrulation bears little resemblance to the body plan in the adult” is true or false. Concept introduction: Gastrulation is the process of formation of the three-germ layered gastrula from the blastula. From the gastrula, organogenesis occurs by morphogenetic movements which later lead to development of the complex adult organism.
