What does each proglottid of a tapeworm contain?

Each proglottid of a tapeworm contains male and female reproductive organs, which is a defining characteristic of these segments. Proglottids are the individual segments that make up the body of a tapeworm, and they play a crucial role in reproduction. As a tapeworm grows, it continues to produce new proglottids, each capable of producing eggs.

The presence of both male and female reproductive structures in a single proglottid allows tapeworms to be hermaphroditic, meaning they can reproduce with themselves or with other tapeworms. When mature, the eggs produced in the proglottids are released into the environment, contributing to the tapeworm's life cycle and potential spread to new hosts.

In contrast, other options reflect different biological functions or structures not associated with proglottids. Digestive cells are not found in proglottids because tapeworms absorb nutrients directly from the host's gut through their skin. Flame cells, associated with excretory functions, are found in flatworms but not specifically related to proglottids. Teguments refer to the outer layer of the tapeworm, which provides protection, but they do not describe the content
