In spite of the name, germ layers have nothing to do with germs or getting sick. A germ layer is a layer of cells in a developing embryo. Each germ layer interacts with the adjacent layer as the ...

The internal organs and the organ systems are directly formed with the help of the embryonic germ layers. Every layer is specific for the production of specific organ systems, which makes them different from one another. This is why any deformity in any germ layer results in the deformity in the organism's development. Answer and Explanation: 1
