Explanation:
Ascaris is a roundworm which belongs to the phylum Nematoda. It is a multicellular organism and like all other multicellular organisms, it has different body cavities for different organs. The body cavity of Ascaris is called a pseudocoelom because:
1. Not lined by coelomic mesoderm: The coelom is a body cavity lined by mesodermal cells. In the case of Ascaris, the body cavity is not lined by mesodermal cells but by a layer of mesenchyme. Therefore, the body cavity of Ascaris is not a true coelom.
2. Derived from blastocoel: In the early embryonic stage, the body cavity of an animal is formed from the blastocoel, which is a cavity within the blastula. In the case of Ascaris, the body cavity is not derived from the blastocoel, but from the space between the endoderm and mesoderm layers.
3. It has giant mesodermal cells: Ascaris has giant mesodermal cells that produce eggs and sperm, and these cells are not found in a true coelom.
4. Derived from archenteron: The archenteron is the primitive gut that forms during gastrulation. In the case of Ascaris, the body cavity is not derived from the archenteron but from the space between the endoderm and mesoderm layers.
Therefore, the correct answer is option A, i.e., the body cavity of Ascaris is called pseudocoel because it is not lined by coelomic mesoderm.
