Amoeba takes in food through temporary extensions of the cell surface, forming a food vacuole. Complex substances inside the food vacuole are broken down into simpler ones, diffusing into the cytoplasm, and undigested material is expelled at the cell surface.

Amoebas, single-celled organisms, ingest food through phagocytosis. Pseudopods extend to surround prey or organic particles, forming a temporary food vacuole. Digestive enzymes break down engulfed material within the vacuole, releasing nutrients. Waste is expelled as the vacuole merges with the cell membrane. This process, lacking specialized organs, exemplifies amoebas’ simplicity in nutrient acquisition and digestion.
