Question
Explain the process of nutrition in Amoeba.
Solution
Amoeba shows holozoic nutrition which comprises Ingestion, Digestion, Absorption, Assimilation and Egestion.
-
Ingestion : Amoeba traps food particles through fingerlike projections called 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 the expulsion of waste materials from the cell.
