Answer:
The three major classes of Platyhelminthes are Turbellaria, Trematoda, and Cestoda.
Explanation:
Platyhelminthes are divided into:
- Turbellaria are also known as free-living flatworms and are typically found in freshwater only. They have a dorsoventrally flattened body, which is flat from the lower and upper surfaces. Example- Planaria.
- Cestoda or tapeworms are flat parasites that mainly cause GI tract (Gastrointestinal tract) infections in the host. Example- Taenia solium
- Trematoda are Flukes that majorly depend on freshwater hosts. Example- Fasciola hepatica.
