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.
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.
Statement II: In cockroach, arolia help in locomotion on smooth surfaces; plantulae help on rough surfaces.
Show Hint
Tegmina = protective forewings in cockroach. True wings for flight = hindwings.

- Both I and II are true
- Both I and II are false
- I true, II false
- I false, II true
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
- 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.
