Which of the following is true regarding the worm phyla?
- Annelida, Platyhelminthes, and Nematoda all have animals with a coelom.
- Annelida, Platyhelminthes, and Nematoda include animals with bilateral body plans.
- Annelida, Platyhelminthes, and Nematoda include animals that are all parasites.
- Annelida, Platyhelminthes, and Nematoda include animals that live in water only.
All worms--annelids, flatworms, and nematodes--have bilateral body plans. Annelids are the only worms with a coelom. Flatworms and nematodes are made up mostly of parasites. All worms are terrestrial, freshwater, or marine animals.

Which of the following are features that help group annelids into their particular classes?
- presence of segments and tentacles
- presence of setae and parapodia
- presence of setae and segments
- presence of suckers and parapodia
Annelids are segmented worms and are classified into three classes--Polychaeta, Oligochaeta, and Hirudinea--depending on the presence of setae and parapodia. Polychaetes have both setae and parapodia, Oligochaetes have setae only, and Hirudineates have neither setae nor parapodia.

Which of the following is true of worms?
- Annelids are the simplest type of worm, lacking a coelom. Nematodes and flatworms are the most complex worms, containing coeloms.
- Annelids live in marine environments only. Flatworms live in freshwater only. Nematodes are the only terrestrial group of worms.
- Annelids include the earthworms that benefit soil by aerating and fertilizing it. Flatworms and nematodes include many intestinal parasites.
- Annelids include a wide variety of intestinal parasites. Nematodes include the earthworms that benefit soil by aerating and fertilizing it.
Annelids include the segmented worms, like the earthworm, that enrich soil by eating their entire weight in soil daily, creating tunnels that aerate the soil. The earthworms also fertilize the soil with their nutrient-rich feces. Flatworms and nematodes include many parasites, including intestinal parasites. Annelids are highly complex with a coelom and many organ systems. Flatworms and nematodes are simple worms that lack a coelom and highly developed organ systems.
