The term "pseudocoelom" refers to how the body cavity appears in the embryo of an organism. As you probably know, the bilaterians (all organisms with left-right symmetry, and the echinoderms for phylogenetic reasons) have three layers of tissue in the embryo: the ectoderm, endoderm, and mesoderm. In the "true" coelomates, the body cavity ("coelom") is completely surrounded by mesodermal tissue. In the pseudocoelomates, though, the body cavity is partly surrounded by mesoderm but partly surrounded by endoderm.
It should be noted that, given our current understanding, the pseudocoelomates do not form a valid taxonomic group. In previous years, the various groups of pseudocoelomates, including the roundworms (Phylum Nematoda), wheel animals (Phylum Rotifera), and others were lumped into one group called the "ascelminthes". Modern fossil and genetic evidence, however, shows that the pseudocoelom has appeared multiple times independently in the animal kingdom.

∙ 14y agoYes, they are pseudocoelmate animals, because they are thicker in body shape than a flatworm ancestor.
It also has a body cavity that isn't found in Acoelomate Flatworms.

Where do the internal organs of Ascaris attach to the body wall?
The digestive tract and reproductive organs of an Ascaris are free floating within the body and do not attach to the body wall. Ascaris do not have any other internal organs other than the gut and internal reproductive organs, as breathing and waste excretion are handled externally within the body wall.

Ascaris is basically a roundworm, to be honest I am nothing close to an expert but I can tell you they are parasites which live in mammals digestive tracts. Phylum nematode symmetry bilateral. Thats about all I can tell you off the top of my head, I hope this helps someone down the line.
