A remarkable property found in aschelminthes which helps them survive in extreme conditions is _____.

• A. Dioecious nature
• B. Cryptobiosis
• C. The presence of pseudocoelom
• D. Parasitic mode of nutrition

Answer 1

The correct option is B

Cryptobiosis

In addition to developing characters like a pseudocoelom, dioecious condition etc., roundworms exhibit a remarkable property called cryptobiosis, which is a reversible physiological state in which metabolic activity is temporarily halted or reduced to an undetectable level without disappearing altogether. It helps them survive periods of extremely dry conditions.
