Final Answer

a. True

Explanation

Tapeworms, which belong to the class Cestoda, are indeed characterized by two primary structures: the scolex and proglottids. The scolex is the head of the tapeworm and is equipped with hooks and suckers that allow it to attach to the intestinal wall of its host. This attachment is crucial for the tapeworm's survival, as it allows the organism to absorb nutrients directly from the host's digestive system without needing a mouth or digestive tract.

Proglottids, on the other hand, are the segments that make up the body of the tapeworm. Each proglottid is capable of reproducing and contains both male and female reproductive organs, enabling the tapeworm to reproduce efficiently within its host. As the tapeworm grows, older proglottids, located at the posterior end, are continuously shed and expelled in the host's feces, which can lead to the transmission of eggs to new hosts. Therefore, the presence of both scolex and proglottids is a defining feature of tapeworms.
