In cockroach, identify the incorrectly matched pair:
Show Hint
Mushroom gland and Phallic gland are separate accessories in the male reproductive system!
Updated On: Jun 10, 2026
- Colleterial glands - forms ootheca
- Seminal vesicles - stores sperms
- Phallic gland - mushroom shaped gland
- Pheromones - chemocommunication
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Reproductive system of the cockroach.
Step 2: Analysis
* (A) Correct: Colleterial glands produce the ootheca. * (B) Correct: Seminal vesicles store sperms. * (C) Incorrect: The mushroom-shaped gland (or utricular gland) is a distinct structure in males, while the phallic gland (or conglobate gland) is a separate structure used in the formation of the spermatophore; they are not synonymous. * (D) Correct: Pheromones are used for chemical communication.
Step 3: Conclusion
The phallic gland is incorrectly matched with the mushroom-shaped gland.
Final Answer: (C)
