WebThe embryo during this stage is called a gastrula. Gastrulation results in three important outcomes: The formation of the embryonic tissues, called germ layers. The germ layers include the endoderm, ectoderm, and mesoderm. Each germ layer will later differentiate into different tissues and organ systems. WebThe inner sphere, or germ layer, is called the endoderm, and the outer germ layer is called the ectoderm. Gastrulation is when the first hollow ball of cells formed during development folds in to form a second sphere. The outer sphere is the ectoderm and the inner sphere is the mesoderm. Embryos of complex organisms, like humans, form three ...
