Explain the process of nutrition in Amoeba.

Amoeba shows holozoic nutrition which is comprised of Ingestion, Digestion, Absorption, Assimilation and Egestion.

Ingestion:

Ameoba traps food particles through fingerlike projections called as pseudopodia. Pseudopodia present outside its body and helps in taking food along with water

Digestion:

Food vacuoles are made after ingesting the food. Enzymes are released in the food vacuole for digestion.

Absorption:

After digestion, nutrients enter the cytoplasm through osmosis.

Assimilation:

Nutrients are utilized by the cell for various purposes.

Egestion:

Food vacuole goes near the cell membrane to empty its contents outside the cell. This results in expulsion of waste materials from the cell.
