Worked practice questions

Which of these is the largest among typical cells/structures?

  1. ostrich egg
  2. mycoplasma
  3. bacterium
  4. human RBC
Show answer and solution

Correct answer: A. ostrich egg

The ostrich egg (a single cell) is the largest mycoplasma are the smallest known cells, bacteria small, RBC ~7µm.

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).
