All of the following are true for Platyhelminthes except____________?
Correct answer: C. Coelomate
- A. Flatwarms
- B. Triploblastic
- C. Coelomate
- D. Bilateral symmetry
Explanation
Platyhelminthes are triploblastic, bilaterally symmetrical flatworms, but they are acoelomate rather than coelomate because the space between the organs is filled with mesenchyme. Students may choose flatworms as the exception by treating the common name as informal, but it is a correct characteristic.
