✏Special excretory organs are absent in unicellular organisms like amoeba.

✏Amoeba possesses osmoregulatory organelle called contractile vacuole.

✏It collects water and wastes from the body, swells up, rea . ches the surface and bursts to release its content to outside.

✏The main excretion takes place through body surface by simple diffusion.

✏The waste material carbon dioxide is removed by diffusion through the cell membrane.

✏In unicellular organism excretory organs are absent and thus excretion takes place through the process of simple diffusion.

✏Fresh organism like amoeba possess osmoregulatory organelle called the contractile vacuole which collects water and waste produced in the body, swells up and reaches the surface and bursts to release its contents outside.
