A germ layer, occasionally referred to as a germinal epithelium, is a group of cells, formed during animal embryogenesis. Germ layers are particularly pronounced in the vertebrates; however, all animals more complex than sponges (eumetazoans and agnotozoans) produce two or three primary tissue layers (sometimes called primary germ layers). Animals with radial symmetry, like cnidarians, produce two germ layers (the ectoderm and endoderm) making them diploblastic. Animals with bilateral symmetry produce a third layer between these two layers (appropriately called the mesoderm) making them triploblastic. Germ layers eventually give rise to all of an animal's tissues and organs through the process of organogenesis.

What are the layers in the gastrula?

The three primary germ layers in the gastrula are the ectoderm (outer layer), mesoderm (middle layer), and endoderm (inner layer). Each layer gives rise to different tissues and organs in the developing embryo.
