Question

Turbellarian epidermis differs from Trematodes due to

• A. Presence of rhabdites
• B. Presence of non-living cuticle in trematodes
• C. Presence of cilia
• D. All of the above

Answer 1

The correct option is C Presence of cilia

Platyhelminthes is the phylum which contains flatworms. These are divided into four major classes: Cestoda, Trematoda, Monogenea, and Turbellaria.

Turbellaria is one of the traditional subdivisions of the phylum Platyhelminthes and includes all the sub-groups that are exclusively not parasitic. The name 'Turbellaria' refers to whirlpools; of the microscopic particles created close to the skins of the aquatic species by the movement of their cilia. Trematodes or flukes are flattened oval or worm-like animals. They are characterized by a sucker around their mouth and an additional ventral sucker. Thus, turbellaria has cilia whereas trematodes don't .
So, the correct answer is option C.
