What are the main differences between roundworms and flatworms?
DIfferent Forms, Different Functions A flatworm has a thin, dorsoventrally flattened body. Roundworms are more cylindrical in shape and tapered to a fine point at one end.

How do flatworms and roundworms reproduce?
Flatworm Reproduction Fragmentation, also called cloning, occurs when a flatworm splits off a part of its body, allowing the separated portion to regenerate into a new worm. With budding, a flatworm grows an extension from its body. This extension, or bud, becomes a new worm and separates from the original flatworm.
