Question

describe the process of nutrition in amoeba ?​

Answer 1

The various steps involved in the process of nutrition are:

Ingestion:

Amoeba ingests food with the help of its finger-like extensions, called pseudopodia. When a food particle approaches Amoeba, it forms pseudopodia around it and forms a food vacuole inside the Amoeba.

Digestion:

Various enzymes from the cytoplasm enter into the food vacuole and break them down into simple soluble molecules.

Absorption:

The simple soluble food is absorbed by cytoplasm of Amoeba from food vacuoles through the process of diffusion.

Assimilation:

Amoeba cell obtains energy from the absorbed food through respiration. This energy is utilised by Amoeba for its growth and repair of the body.

Egestion:

When a considerable amount of undigested food gets collected inside Amoeba, its cell membrane ruptures and throws out the undigested food.
