- How do body structures and functions of a flatworm compare with those of a cnidarian for
- sensory responses to the environment?
- arrangement of the nervous system?
- obtaining food?
- movement?
- excretion of body wastes?
- What is the flatworm’s shape? What type of symmetry does it have?
- How does the free-living flatworm move? How does its shape relate to its method of moving? What structures are necessary for this type of movement?
- How does the digestive system of a nematode or annelid differ from that of a flatworm? In what ways is the digestive system of an annelid worm more efficient than that a flatworm?
- Compare the excretory systems of a flatworm and an annelid worm. How are they similar? How are they different?
- What is a coelom? What advantages does an animal with a coelom have over an animal, such as a flatworm, that has no coelom?
- Fill in Table 3.4 comparing the body structures of a sea anemone, a flatworm, a nematode, an annelid worm, and a fish. Are flatworms more like cnidarians or annelids? Are annelids more like flatworms or fish? Give evidence that supports your answer.
