Detailed explanation-1: -The endoderm gives rise to the gastrodermis, the tissue that lines the gut cavity. The animals which possess all these 3 layers including ectoderm, mesoderm germ layer (in between), and endoderm, are commonly called triploblastic animals.

Detailed explanation-2: -Endoderm cells give rise to certain organs, among them the colon, the stomach, the intestines, the lungs, the liver, and the pancreas. The ectoderm, on the other hand, eventually forms certain “outer linings” of the body, including the epidermis (outermost skin layer) and hair.

Detailed explanation-3: -The endoderm develops into the gastrodermis, which lines the gastrovascular cavity. The ectoderm develops into the epidermis, which covers the outside of the body.

Detailed explanation-4: -Mesoderm gives rise to the connective tissue, including the wall of the gut tube and the smooth muscle. Endoderm is the source of the epithelial lining of the gastrointestinal tract, liver, gallbladder, pancreas.

Detailed explanation-5: -The ectoderm provides a protective function analogous to the one of epidermis whereas the endoderm, also named gastrodermis as it lines the surface of the gastric cavity, is involved in food uptake and digestion.
