Answer 2

Answer:

Acoelomate - Flatworms (phyla Platyhelminthes, Nemertea, and Mesozoa) lack a coelom, although nemerteans have a fluid-filled cavity at their anterior, or head, end, which is used to eject the proboscis rapidly. The lack of a fluid-filled cavity adjacent to the muscles reduces the extent to which the muscles can contract and the force they exert. Other examples - Spongilla, sea anemone, Planaria, liver fluke, etc.

Pseudocoelomate animals have a pseudocoelom (literally “false cavity”), which is a fully functional body cavity. Tissue derived from mesoderm only partly lines the fluid filled body cavity of these animals. Thus, although organs are held in place loosely, they are not as well organized as in a coelomate. Example - Wuchereria, Ascaris.

Coelomate animals or Coelomata ( "true coelom") have a fluid filled body cavity called a coelom with a complete lining called peritoneum derived from mesoderm. Example - Nereis, Earthworm, Scorpion, Birds, Fishes, Horse.
