Mitochondria

None of these

• A. Contractile vacuoles
• B. Endoplasmic reticulum
• C. Mitochondria
• D. None of these

Answer 1

Answer: (A), (D)

The correct option is A

Explanation of the correct option

1. Single-celled organisms do not have complex mechanisms for the process of excretion; they remove wastes by simple diffusion through the cell membrane into the surrounding
2. Amoeba produces some nitrogenous wastes which are transported out of its body through the plasma membrane by diffusion.
3. A contractile vacuole works just the same as the name suggests, in that it expands and contracts.
4. Contractile vacuole plays a role in excretion.
5. It keeps the osmotic equilibrium in check, and aids in the elimination of surplus water from the body of the amoeba.

Final Answer: Excretory organs in Amoeba are Contractile vacuoles.
