Question

Which one of the following is a wrong match?

• A. Platyhelminthes - No coelom
• B. Chordata - Schizocoelom
• C. Nematoda - Pseudocoelom
• D. Arthropoda - Haemocoel

Answer 1

The correct option is B Chordata - Schizocoelom

Platyhelminthes are the group of flat worms. They are acoelomates. There is no coelom present in these worms.

Chordates are the organisms which are characterised by the presence of notochord. They are coelomates as they have true coelom.

Nematodes are pseudocoelomates. They are having three-layered body that has a fluid-filled body cavity (pseudocoelom) between the endoderm and the mesoderm.

Arthropods have a hemocoel. There is an open body cavity in which blood flows and bathes the tissues and organs.

Thus, the correct answer is option B.
