Quizplus · Accepted Answer

The letter "C" represents mesoderm, which is one of the primary germ layers that forms during gastrulation. Ectoderm and endoderm are the other two primary germ layers, while the neural plate is a precursor to the nervous system that forms from ectoderm. Yolk is a nutritive material that is found within the cytoplasm of the egg cell.
