Worked practice questions

Diploblastic animals have two embryonic germ layers — ectoderm and:

  1. Mesoderm
  2. Endoderm (with undifferentiated mesoglea in between)
  3. Notochord
  4. Spongocoel
Show answer and solution

Correct answer: B. Endoderm (with undifferentiated mesoglea in between)

**Diploblastic:** ectoderm + endoderm + mesoglea (undifferentiated layer) between them. Coelenterates are diploblastic. Triploblastic animals add a third true layer — mesoderm — between ectoderm and endoderm (Platyhelminthes onwards).
