Question

Statement I: First pair of wings in cockroach help in flight and are called tegmina.
Statement II: In cockroach, arolia help in locomotion on smooth surfaces; plantulae help on rough surfaces.

• A. Both I and II are true
• B. Both I and II are false
• C. I true, II false
• D. I false, II true

Hint:

Tegmina = protective forewings in cockroach. True wings for flight = hindwings.

Answer 1

The Correct Option is B

- Statement I is false because tegmina are the first pair of forewings, but they are non-functional in flight; they only protect the hindwings. 
- Statement II is also false; while arolium and plantulae do help in grip, their described functions are incorrectly attributed.
