Flatworms are considered acoelomate, since they have no body cavity, and roundworms are pseudocoelomate because they have a body cavity, but it is not derived from the splitting of the mesoderm tissue. Also, flatworms only have one opening in their digestive system unlike roundworms with two.
Roundworms are nematodes. They have muscles to help them move. They actually have two openings. They have a mouth, complete digestive tract, and anus for excreting waste.
Ascaris lumbricoides is the name of one of the more widely known roundworm. All roundworms including Ascaris lumbricoides belongs to phylum Nematoda.
The mouth is only one opening into the human body.

Roundworms are particularly fond of tomato plants. Other roundworms live inside plant tissues, where they cause considerable damage. ChaCha!
