Vedclass · Answer

(A) $Acoelomates$ are animals that lack a body cavity or coelom. Examples include $Porifera$,$Cnidaria$,$Ctenophora$,and $Platyhelminthes$.In $pseudocoelomates$,the body cavity is a $pseudocoelom$ or false coelom,which is not lined by mesoderm. Examples include $Aschelminthes$.In $coelomates$,the body cavity is a true coelom,which is lined by mesoderm on both sides. Most phyla from $Annelida$ to $Chordata$ are $coelomates$.$Molluscs$ and $Insects$ (Arthropoda) are $coelomates$,while $Flatworms$ are $acoelomates$.Therefore,the statement that $Roundworms$ $(Aschelminthes)$ are $pseudocoelomates$ is correct.
