D) Porifera
E) Platyhelminthes
Correct Answer: E
Solution :
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.You need to login to perform this action.
