The incorrect statement about classification on the basis of coelom is option 'D', which states that in coelomates, cavities between the gut wall and mesoderm are absent.
Coelom is the fluid-filled cavity present within the mesoderm of many animals. It separates the body wall from the gut wall and plays a crucial role in providing space for internal organs to develop and function properly. Coelomates, acoelomates, and pseudocoelomates are three classifications based on the presence or absence of coelom.
Coelom:
- Coelom is a fluid-filled space located between the body wall and gut wall in many animals.
- It is derived from the mesoderm during embryonic development.
- The presence of coelom allows organs to move and function independently, providing flexibility and protection.
Coelomates:
- Coelomates are animals that possess a true coelom.
- True coelom is a cavity completely lined by mesodermal tissue.
- In coelomates, the coelom is surrounded by mesodermal tissue both on the outer side (body wall) and inner side (gut wall).
- Examples of coelomates include annelids, mollusks, arthropods, echinoderms, and chordates.
Acoelomates:
- Acoelomates are animals that lack a coelom.
- They do not have a fluid-filled cavity between the body wall and gut wall.
- The space between the body wall and gut wall is filled with solid mesodermal tissue.
- Examples of acoelomates include flatworms (Platyhelminthes) such as planarians, tapeworms, and flukes.
Pseudocoelomates:
- Pseudocoelomates are animals that possess a pseudocoelom.
- Pseudocoelom is a fluid-filled cavity that is partially lined by mesoderm.
- The coelom is not completely surrounded by mesodermal tissue.
- The space between the body wall and gut wall is partially filled with mesoderm and partially with non-mesodermal tissue.
- Examples of pseudocoelomates include roundworms (Nematoda) such as Ascaris, hookworms, and filarial worms.
Incorrect Statement:
The statement in option 'D' is incorrect because in coelomates, the cavities between the gut wall and mesoderm are not absent. In fact, coelomates have a true coelom that is completely surrounded by mesodermal tissue on both the outer and inner sides. The presence of coelom is a distinguishing feature of coelomates.

Coelom is the cavity between the body wall and gut wall. It is the fluid filled space other than lymph vessels and blood vessels. Animals are divided into coelomates, acoelomates and pseudocoelomates based on the presence or absence of the coelom or false coelom respectively.
