Excretory organs of Ascaris are

• A. Kidney
• B. Flame cell
• C. Renette Glands
• D. Nephridia

Ascaris, a type of parasitic roundworm, has a unique system for excretion. Unlike mammals that use kidneys, Ascaris relies on specialized structures for this purpose.

Excretory Structures in Ascaris

The correct answer to your question is:

• C. Renette Glands

Renette glands are responsible for excreting waste products in Ascaris. They help maintain the worm's internal environment by removing excess water and metabolic wastes.

Other Options Explained

• A. Kidney - This organ is found in vertebrates, not in Ascaris.
• B. Flame cell - These are found in flatworms, not roundworms like Ascaris.
• D. Nephridia - While these are excretory structures in some worms, Ascaris specifically uses renette glands.

Understanding the excretory system of Ascaris helps in grasping how different organisms adapt their biology to survive in various environments.
