Justify the statement. Ascaris is described as a pseudocoelomate.
Asked by Topperlearning User | 10th Jul, 2014, 01:14: PM
In pseudocoelomates, the body cavity is not lined by the mesoderm. Instead, the mesoderm is present in the form of pouches scattered between the ectoderm and the endoderm. The same arrangement of the three germinal layers is found in Ascaris. Hence, it is described as pseudocoelomate.
