Explain how the processes of gastrulation and organogenesis are related
What will be an ideal response?
Gastrulation is the rearrangement and migration of the cells of the bilaminar embryonic disc to form the trilaminar embryonic disc. Trilaminar means, "having three layers," so this is the stage at which the three germ layers develop. The three germ layers will become all of the major organ systems in the process of organogenesis by the end of week 8. In the process of organogenesis, the three primary germ layers differentiate into organs and organ systems.
