In cockroach, excretion is brought about by:

A. Phallic gland

B. Urecose gland

C. Nephrocytes

D. Fat body

E. Collaterial glands

Choose the correct answer from the options given below:

  1. A

    A and E only

  2. B

    A, B and E only

  3. C

    B, C and D only

  4. D

    B and D only

Solution

Cockroach excretion is performed primarily by Malpighian tubules, plus urecose glands, nephrocytes and the fat body — so B, C and D are correct. Phallic glands and collaterial glands belong to the reproductive system (male and female respectively) and are not excretory organs.
