Question

Quizplus · Accepted Answer

Strobila is a long chain of proglottids (segments) that contain bags of eggs in tapeworms. The strobila is located at the end of the tapeworm and is responsible for producing and releasing eggs. Cercariae are the swimming, free-living larvae of trematode parasites. Sporocysts are the initial sac-like stage of the life cycle of some parasites. Scolex is the head of the tapeworm, which attaches to the intestinal wall of the host. Hydatid is a fluid-filled cyst that can develop in the liver or lungs of a host infected with the tapeworm Echinococcus. None of these terms describes the long chain of bags of eggs in a tapeworm.
