Germ layers give rise to all of animal's tissue and organs.
The chordamesoderm is the part of the mesoderm (one of the 3 germ layers in a developing embryo) that gives rise to the notochord.
The parenchyma cells tissues give rise to the cork cambium.

Mesoderm
Mesoderm forms muscles .
All from Mesoderm, except the eye muscles that originate from ectoderm
Mesoblasts are a type of embryonic stem cell that give rise to the mesoderm, one of the three primary germ layers in early development. Mesoderm gives rise to various tissues and structures in the body, including muscle, bone, cartilage, and blood vessels. Mesoblasts are important for tissue development and regeneration.
Glands
Actually ur question is itself not correct so the 'WHY" part cannot be answered. Epithelial tissue is a lining tissue which can be present in any organ.the mesoderm gives rise to organs like-muscles / bones / connective tissue / blood and lymph vessels / kidney / gonads and the cortex of suprarenal glands. ectoderm-nervous system epidermis and so on and endodermto GIT liver lungs pancreas and GIT so for example if u consider the epithelial tissue of lungs----its derived from endodermas lung as a whole is derived from endoderm.
Many arterioles that penetrate the Submucosa give rise to capillary networks that supply the Intestinal Glands and villi with blood.
The ectoderm is the germ layer covering the surface of the embryo and develops into the outer covering of the animal (in our case, our skin) and in some phyla, the nervous system. The mesoderm forms the muscles and most other organs between the digestive tract and the outer covering of the animal. The endoderm, which is the innermost germ layer, lines the developing digestive tube (referred to as the archenteron) and gives rise to the lining of the digestive tract or cavity and organs derived from it, such as the liver and lungs.
epiblast is a layer formed by differentiation in the inner mass cell.cells at the posterior end of this epiblast form a bulge called primitive streak.gives rise to embryonic mesoderm and ectoderm
The three embryonic tissue layers of animals are as follows: the endoderm, the mesoderm, and the ectoderm. Each layer gives rise to different parts of the animal.
