Soft bodied invertebrates classified into three groups based on body structure are flatworms, roundworms, and segmented worms. Flatworms have a flattened body, roundworms are cylindrical with a tapered ends, and segmented worms have distinct body segments.
There is no such thing. 'Organelle' is the specialised structure within a cell. It has no relevance to 'locomotion'.
Roundworms, or nematodes, are unsegmented, cylindrical worms with a tough outer cuticle and a simple body structure, lacking specialized respiratory and circulatory systems. In contrast, annelids, such as earthworms, are segmented and have a more complex body structure with a true coelom, allowing for a more advanced circulatory system and segmentation that facilitates movement. Additionally, annelids possess setae (bristle-like structures) for locomotion, while roundworms do not. These differences highlight the distinct evolutionary adaptations of each group within the animal kingdom.
Tapeworms belong to the class Cestoda, which is a class of parasitic flatworms. They have a long, segmented body with a unique structure called a scolex that allows them to attach to the intestines of their hosts.
flatworms are the only triploblastic organisms that lack a coelom

Roundworms have long, cylindrical bodies that taper at both ends. They have a complete digestive system with a mouth and an anus, and their bodies are covered in a protective cuticle. Roundworms also have a fluid-filled body cavity called a pseudocoelom.
Roundworms are classified as invertebrates because they lack a backbone or spinal column, which are defining characteristics of vertebrates. Instead, roundworms have a simple, unsegmented body structure with a tough outer cuticle for protection.
Yes. Flatworms lack a skeletal structure, and any creature without a skeletal structure is classified as an invertebrate.
