Question

What tissue type comes from all 3 embryonic germ layers?

1) Endoderm
2) Mesoderm
3) Ectoderm
4) All of the above

Answer 1

None of the embryonic germ layers including ectoderm, mesoderm, or endoderm individually gives rise to tissues derived from all three germ layers; they each have specific derivatives in the embryo's development.

Step-by-step explanation:

The tissue type that comes from all three embryonic germ layers is not any of the layers themselves, but rather specific types of tissues and organs that develop from these layers in the embryo. The ectoderm gives rise to the nervous system and the epidermis, mesoderm gives rise to muscle cells and connective tissue, and the endoderm gives rise to the gut and many internal organs. Thus, no single germ layer can create all tissue types; each layer has a specific set of tissues and organs it develops into.
