Differbetween
Platyhelminthes refers to a phylum of worms having bilateral symmetry and a soft, usually flattened body, comprising flatworms while Aschelminthes refers to an invertebrate animal belonging to a group of phyla that are distinguished by the lack of a well-developed coelom and blood vessels.

What is the main difference between platyhelminthes and nematoda?
Platyhelminthes and Nematoda are two invertebrate animal phyla. Platyhelminthes consists of flatworms whereas Nematoda consists of roundworms. The main difference between Platyhelminthes and Nematoda is the anatomical structure of the body of each invertebrate.
Are Aschelminthes and nematoda same?
The Aschelminthes (also known as Aeschelminthes, Nemathelminthes, Nematodes), closely associated with the Platyhelminthes, are an obsolete phylum of pseudocoelomate and other similar animals that are no longer considered closely related and have been promoted to phyla in their own right.

What is the definition of platyhelminthes?
: a phylum of soft-bodied bilaterally symmetrical usually much flattened invertebrates comprising the planarians, flukes, tapeworms, and related worms, having the body unsegmented or composed of a series of proglottids formed by strobilation, built up of ectoderm, endoderm, and mesoderm, and without body cavity, the ...
Which organisms are included under platyhelminthes Why?
Planaria, Fasciola(liver fluke), Taenia solium(pork tape worm), Taenia saginata (beef tape worm) are examples of platyhelminthes. Theses organisms are included in platyhelminthes because they have same properties of platyhelminthes organisms like flattened body, bilateral symmetry and have organ level of organisation .
Why Aschelminthes are called Pseudocoelomates?
In Aschelminthes, the body cavity is not lined by mesoderm, instead, the mesoderm is present as scattered pouches in between the ectoderm and endoderm. Hence, they are called pseudocoelomates.
Why Aschelminthes are called nematodes?
The body of Aschelminthes is circular in cross section hence they are called as roundworms. Aschelmintge when cut are circular in cross section area.so they are called round worms. Aakash EduTech Pvt.
What are the two types of nematodes?
The two nematode classes, the Chromadorea and Enoplea, have diverged so long ago, over 550 million years, that it is difficult to accurately know the age of the two lineages of the phylum (Figure 1). Figure 1. Nematodes are multicellular animals in the group Ecdysozoa, or animals that can shed their cuticle.
Which of the following is correct about Ascaris?
Ascaris requires a single host, i.e., man to complete its life cycle. The most important locations in body of man where Ascaris visits are small intestine and from there it migrates to the lungs through pulmonary circulation where they almost ten times bigger and moult twice. Thus, the correct answer is option C.
Who gave the term Aschelminthes?
The phylum name “Nemathelminthes” was coined by Gegenbaur. The term “Aschelminthes” was proposed by Grobben.
Which type of Coelom is present in Aschelminthes?
Ans: The body cavity of phylum Aschelminthes is called pseudocoelom. It is filled with pseudocoelomic fluid. The body cavity is not lined by the mesodermal layer.
