What.are.the.process.nutrition.in.amoeba.

Amoeba follows holozoic mode of nutrition in which the solid food particles are ingested which are then acted upon by enzymes and digested.

• Amoeba engulfs food by temporary finger-like projections of its body surface called pseudopodia.
• When a pseudopodium fuses with the food particle, it forms a food vacuole.
• Complex substances are broken down into simple substances inside the food vacuole. These simple substances are then diffused into the cytoplasm.
• The remaining unwanted material is taken to the cell surface and is thrown out.

Nutrition in Amoeba: Amoeba is omnivorous. i.e. it feeds on smaller animals, plants, micro-organisms and fragments of larger organisms. Nutrition is holozoic. Ingestion can occur at any place on the surface since a regular mouth is absent. Ingestion occurs through phagocytosis or engulfing the food particle in an invagination of the body. The engulfed food particle comes to lie inside a food vacuole. The latter is surrounded by a membrane.
Digestion: The digestion is intracellular and the food vacuoles act as temporary stomach for digestion.
Absorption:  It occurs by diffusion and distribution takes place by cyclosis.
Assimilation: Assimilation of digested material occurs in a single cell.
Egestion:  The undigested food is eliminated through the surface of the cell, where the food vacuole containing the undigested food bursts and discharges its contents to the outside.
