Question

Explain the process of nutrition in amoeba

Answer 1

Amoeba ingests the food by encircling it by forming pseudopodia. When the food is completely encircled , the food is engulfed in the form of a bag called food vacuole. Digestion is the process of breaking the large and insoluble molecules in small and water soluble molecules.

Answer 2

An An amoeba is a type of single-celled protozoal organism. Nutrition in an amoeba occurs through a process called phagocytosis where the entire organism pretty much engulfs the food it plans on eating up. The image below summarizes the stepwise process through which nutrition in amoeba occurs.



 

This food is mostly tiny bacteria, algae or other plant or dead animal matter available in the surrounding of the amoebas. One wonders how these amoebas, which do not have a mouth and no suction mechanism actually take in food since they’re just these shapeless cells.

Mode of Nutrition

The cell contents are enclosed by a shapeless cell membrane. Inside the cell, there is a dense nucleus, some bubble like contractile vacuoles, and all of these are surrounded by cytoplasm. When the amoebas sense some food nearby they move toward it with their pseudopodia (meaning false feet). The amoeba senses some food and gets ready to project itself towards the food partical.
