Which among the following is incorrect about acoelomates?a)Body cavity...
Incorrect statement about acoelomates: Mesoderm holds the internal organs in its own place (Option C)
Explanation:
Acoelomates are a group of animals that lack a body cavity called a coelom. The coelom is a fluid-filled space between the body wall and the digestive tract that provides support, protection, and a space for organ development and movement. Acoelomates have a solid body without a true body cavity.
Key points:
- Body cavity: Acoelomates do not have a body cavity, which means their organs are not surrounded by a fluid-filled space.
- Examples: Coelenterates, also known as Cnidarians, are not the best examples of acoelomates. Coelenterates have a body cavity called a gastrovascular cavity, which is not a true coelom.
- Mesoderm: Mesoderm is one of the three germ layers (ectoderm, mesoderm, and endoderm) that develop during embryonic development. It gives rise to various tissues and organs, including muscles, bones, and circulatory system. Acoelomates lack a true mesoderm layer. Instead, they have a solid, triploblastic body plan without any cavity between the ectoderm and endoderm layers.
- Nematodes: Nematodes, also known as roundworms, do not belong to acoelomates. They are pseudocoelomates, which means they have a body cavity called a pseudocoelom that is partially lined by mesoderm.
Conclusion:
The incorrect statement about acoelomates is that mesoderm holds the internal organs in their own place. Acoelomates lack a true coelom and mesoderm, which are characteristic features of animals with a body cavity. Nematodes, on the other hand, belong to the group of pseudocoelomates, not acoelomates.

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.
