Classify animals on the basis of body cavity or coelom.

Asked by Topperlearning User 4th June 2014, 1:23 PM
Answered by Expert
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.
