Answer:
On the basis of body cavity or coelom animals are grouped into:
i. Acoelomates: These animals do not posses any coelom as the space between the body wall and the digestive tract is filled with parenchymatous tissue.
ii. Pseudocoelomate: The organisms of this group have a coelom but this coelom does not arise from the mesoderm and is not lined by epithelial cells.
iii. Coelomates: The organisms of this group have a true coelom which originates from the mesoderm and lined by epithelial cells of mesodermal origin.
