Vedclass · Answer

(A) In triploblastic animals,the presence or absence of a body cavity between the body wall and the gut wall is very important in classification. $1$. The body cavity which is lined by mesoderm is called the $Coelom$. $2$. Animals possessing this coelom are called $Coelomates$ (e.g.,Annelids,Molluscs,Arthropods,Echinoderms,Hemichordates,and Chordates). $3$. In some animals,the body cavity is not lined by mesoderm,instead,the mesoderm is present as scattered pouches in between the ectoderm and endoderm. Such a body cavity is called a $Pseudocoelom$ and the animals are called $Pseudocoelomates$ (e.g.,Aschelminthes). $4$. Animals in which the body cavity is absent are known as $Acoelomates$ (e.g.,Platyhelminthes). Since the question asks for the common term used for the body cavity in triploblastic animals,$Coelom$ is the standard term for the true body cavity.
