Q.
Triploblastic, unsegmented, acoelomate exhibiting bilateral symmetry and reproducing both asexually and sexually, with some parasitic forms. The above description is characteristic of the phylum
Kingdom-Animalia has been graded on the basis of symmetry as: Radiata (diploblastic animals with radial symmetry eg, Cnidaria) Bilateria (triploblastic animals with bilateral symmetry. Bilateria includes these sections). Acoelomates-Body cavity or coelom is absent eg, flatwormr. Pseudocoelomates-Body cavity is false coelom eg, earthworms. Members Phylum-Platyhelminthes (flat worms) are the only forms, with triploblastic, unsegmented, acoelomate and bilateral symmetry. They reproduce both sexually and asexually and also have some parasitic forms eg, Fasciola, Taenia etc.
