Question

Diploblastic animals possess

• A. Differentiated ectoderm
• B. Differentiated endoderm
• C. Undifferentiated mesoglea
• D. All of these

Answer 1

The correct option is D

All of these

Diploblastic animals are those that develop two germ layers during early embryonic development. These layers are the outer ectoderm and the inner endoderm, along with a gelatinous substance called mesoglea in between. The endoderm differentiates into true tissue. This includes tissue associated with the gut and associated glands. The ectoderm, on the other hand, gives rise to the epidermis, the nervous tissue, and if present, nephridia. The mesoglea does not differentiate into any major tissue; it merely serves as an internal skeleton, supporting the body, along with performing other minor functions.
