Name the process by which Amoeba performs excretion

Amoeba performs excretion by the process of diffusion. Amoeba is a unicellular organism. It does not have specialized organs for excretion. Waste materials like carbon dioxide and ammonia pass directly out of the cell by diffusion. Diffusion is the movement of substances from a region of high concentration to a region of low concentration.

Steps in excretion

• Waste accumulates in the cytoplasm.
• Waste passes through the cell membrane into surrounding water.
• Sometimes contractile vacuoles help in removing excess water and wastes.

Thus, diffusion is the main process of excretion in Amoeba.
