Which among the following is incorrect about acoelomates?a)Body cavity...
Understanding Acoelomates
Acoelomates are a group of animals characterized by the absence of a body cavity (coelom). This classification highlights the differences in body structure and function among various animal groups.
Explanation of the Options
- Option A: Body cavity is absent in these types of organisms
- This statement is correct as acoelomates do not possess a coelomic cavity, which differentiates them from coelomates.
- Option B: Coelenterates are the best examples for acoelomates
- This option is somewhat misleading. While coelenterates (like jellyfish and corals) are indeed lacking a true coelom, they belong to the phylum Cnidaria, which is distinct from traditional acoelomate groups like flatworms (Platyhelminthes).
- Option C: Mesoderm holds the internal organs in its own place
- This statement is incorrect. In acoelomates, the mesoderm does not form a cavity. Instead, the space between the ectoderm and endoderm is filled with a solid mass of tissue. Therefore, the internal organs are embedded in this solid tissue rather than being held in a cavity.
- Option D: Nematodes also belong to acoelomates
- This statement is incorrect. Nematodes, or roundworms, are actually pseudocoelomates. They have a body cavity that is not completely lined by mesoderm, distinguishing them from true acoelomates.
Conclusion
The correct answer is option C, as it inaccurately describes the role of mesoderm in acoelomates. Understanding these distinctions is crucial for grasping the complexity of animal body plans and their evolutionary significance.

Which among the following is incorrect about acoelomates?a)Body cavity...
Body cavity is absent in acoelomates. In this type of animals, mesoderm helps in holding the internal organs in its own place. Coelenterates, platyhelminthes and porifera are the best examples for acoelomates.
