D) endoderm.
E) neural crest cells.

Accepted Answer

The open space within the gastrula is called the archenteron. This is the primitive gut that will eventually develop into the digestive system. The ectoderm, mesoderm, and endoderm are the three primary germ layers that develop in the early stages of embryonic development. Neural crest cells are a group of cells that arise from the ectoderm and can differentiate into a variety of different cell types, including neurons, cartilage, and bone.
