Question

How does excretion take place in Amoeba?

Answer 1

Excretion:

• The separation and discharge of waste materials or harmful chemicals from a plant's or animal's cells and tissues are referred to as excretion.

Excretion in Amoeba:

• Unicellular species like amoeba lacks special excretory organs.
• The contractile vacuole is an osmoregulatory organelle found in amoebae.
• It gathers water and waste from the body, swells up, rises to the surface, then bursts to release its contents into the environment.
• The majority of excretion occurs through simple diffusion across the body's surface.
• Diffusion via the cell membrane removes the waste substance carbon dioxide.
