Question

In phylum Platyhelminthes, the excretory organs are

• A. Nephridia
• B. Malpighian tubules
• C. Flame cells (solenocytes)
• D. Green glands

Answer 1

The correct option is C Flame cells (solenocytes)

• A flame cell is a specialized excretory cell found in flatworms (except the turbellarian order Acoela), rotifers and nemerteans. Flame cells function like a kidney, removing waste materials.
• The nephridium is an invertebrate organ that occurs in pairs and performs a function similar to the vertebrate kidney. Nephridia remove metabolic wastes from an animal's body.
• The malpighian tubule is a tubular excretory organ, numbers of which open into the gut in insects and some other arthropods.

Green glands are excretory organs in Crustaceans.

Therefore, the correct answer is option C.
