Question

Given are the four matches of phyla with their characteristic cells.
A. Coelenterate - Nematocysts
B. Porifera - Choanocytes
C. Ctenophora - Solenocytes
D. Platyhelminthes - Nephrocytes

Mark the option that has both correct matches.

• A. A and B
• B. B and C
• C. C and D
• D. B and D

Answer 1

The correct option is A A and B

Nematocysts are specialized stinging cells specific to coelenterates that act as organs of offence and defense.

Choanocytes are cells that line the interior of asconoid, syconoid and leuconoid body type sponges that contain a central flagellum, surrounded by a collar of microvilli, which are connected by a thin membrane.

Solenocytes is a type of long, narrow, flagellated cell that functions in excretion of nitrogenous wastes in annelids and not Ctenophora.

Nephrocytes is a specialized cell, especially in arthropods, whose function involves the accumulation or formation of waste or excretory products and not Platyhelminthes.

Therefore, the correct answer is option A.
