Question

How does ingestion occur in unicellular animals like an amoeba?

Answer 1

Amoeba does not have organs like hands and mouth.

• It is a unicellular animal. It can take in food through any part of the surface of its unicellular body.
• It surrounds the food particle from all sides to take it into the cell.
• After that, it digests the food with the help of different enzymes.
• Undigested food is left behind as the amoeba moves further with the help of pseudopodia.
• In unicellular animals like an amoeba, euglena, paramecium, etc. all the steps of nutrition occur within their unicellular body.
