ii)Pseudocoelomate
Answers
Answer:
A coelom is a fluid-filled cavity present between the alimentary canal and the body wall. Animals can be divided into three types on the basis of types of coelom namely:
Acoelomates: These are the animals in which there is no cavity present. Most common example is Platyhelminthes. Figure A represents, acoelomates.
Pseudocoelomates: These are the animals in which a body cavity is present in addition to the alimentary canal. Mesoderm is present on the outer body wall and not in the gut. Figure B represents Pseudocoelomates. Examples include Nematodes
Coelomates: In these animals, coelom is lined by mesoderm both on the inside as well as around the gut. Such type of animals can be categorised into schizocoelomates and enterocoelomates. The given C figure represents, Schizocoelomates in which body cavity is formed from the mesodermal tissue. Examples include annelids, arthropods. etc.
Thus, the correct answer is option A.
