• A. Flame cells are excretory structures in flatworms.
• B. Green gland is excretory organs in annelids.
• C. Columns of Bertini are the extensions of the renal cortex into the renal medulla between the renal pyramids.
• D. All are correct
• E. None of the above

Answer 1

Answer: (A), (C)

The correct options are
A Flame cells are excretory structures in flatworms.
C Columns of Bertini are the extensions of the renal cortex into the renal medulla between the renal pyramids.

Green glands are excretory organs of some arthropods like crustaceans. They are also called antennal glands because these glands are located near the base of larger antennae. The excretory organ in annelids is nephridia.

Thus, A and C statements are correct.
