Worked practice questions

In diploblastic animals, which undifferentiated layer lies between ectoderm and endoderm?

  1. Mesoderm
  2. Mesothelium
  3. Mesentery
  4. Mesoglea
Show answer and solution

Correct answer: D. Mesoglea

Diploblastic animals have no true mesoderm; a non-cellular mesoglea sits between the two germ layers.

A true coelom is a body cavity lined by which germ layer?

  1. Ectoderm
  2. Endoderm
  3. Mesoderm
  4. Mesoglea
Show answer and solution

A body cavity counts as a true coelom only when mesoderm lines it.

In a pseudocoelomate, how is the mesoderm arranged?

  1. Lining the whole body cavity
  2. Fused with endoderm only
  3. Absent from the embryo
  4. As scattered pouches
Show answer and solution

Correct answer: D. As scattered pouches

The pseudocoelom is not lined by mesoderm; the mesoderm lies as scattered pouches between ectoderm and endoderm.
