Platyhelminthes examples include which of the following?

• A. Flatworms
• B. Roundworms
• C. Nematodes
• D. Annelids

Answer: (A)

Platyhelminthes are flatworms. They’re characterized by a dorsoventrally flattened body, lack a true body cavity (they’re acoelomates), and often have a simple or no digestive system. This combination of traits places them in a different group from other worm types. Roundworms, or nematodes, are elongated and have a pseudocoelom, while annelids are segmented worms with a true coelom. Because flatworms are the members of Platyhelminthes, the example that fits this phylum is the flatworms.
