Question
Which one of the following statements about certain given animals is correct?
Roundworms (Aschelminthes) are pseudocoelomates.
Mollusks are acoelomates.
Insects are pseudocoelomates.
Flatworms (Platyhelminthes) are coelomates.
Aschelminthes (roundworms) are classified as pseudocoelomates because their body cavity is not lined by mesoderm, but instead contains mesoderm as scattered pouches . The other statements are incorrect: Molluscs and Arthropods (which include insects) are true coelomates, possessing a body cavity lined by mesoderm . Platyhelminthes (flatworms) are acoelomates, meaning they lack a body cavity . This specific question was a part of the AIPMT PRE 2010 examination .
This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from Animal Kingdom. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
