Question Set: Structure and Function

NGSS Science and Engineering Practices:

NGSS Crosscutting Concepts:

  1. How do body plans constrain the types of features that can evolve in organisms?
  2. What are the advantages of a radially symmetrical body plan?
  3. What are the advantages of a bilaterally symmetrical body plan?
  4. Why do bilaterally symmetrical organisms typically have feeding and sensory structures concentrated at the anterior end of the organism?
  5. Use your own words to define the term cephalization. Provide examples of animals with and without cephalization.
  6. Explain why there are fewer body plans in diploblastic compared with triploblastic organisms.
  7. What is a coelom? Explain its importance to complexity of invertebrate body plans.
