Question

describe the process of nutrition in amoeba

Answer 1

Nutrition in amoeba is holozoic. Thus, solid food particles are ingested which are then acted upon by enzymes and digested. It is an omnivore, feeding on both plants and animals. ... Since it is a unicellular organism, amoeba does not have any specialised structure or organ for the process of nutrition.

Answer 2

Amoeba is a unicellular omnivore organism that does not possess specialised organs for the process of Nutrition.The mode of nutrition in Amoeba is holozoic and takes place with the help of a false feet called pseudopodia.

It engulfs the food when it comes in contact with its cell surface by ingestion. Pseudopodia fuses over the food particle to form a food vacuole.


Digestion in Amoeba is intracellular in nature.
Inside the food vacuole , complex food breaks into small soluble molecules, readily absorbed by the cytoplasm. This process is called absorption. The absorbed food further assimilated by Amoeba to derive energy for growth. The undigested food material is removed by the cell membrane., which is called egestion.
