Answer 1

Hey Bro !!

Thanks for the question.

Amoeba is an unicellular organism.

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

⏩ Amoeba posses an osmoregulatory organ called contractile vacuole.

⏩ It collects water and waste from the body, swells up, reaches the surface and burst to release its content to outside.

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

⏩ The waste material co2 is removed by diffusion through cell membrane.
