how does nutrtion takes place in amoeba?

Nutrition in amoeba takes place by phagocytosis. The amoeba develops finger like processes called pseudopodia around the food particle, which fuses with the food forming food-vacuole. Inside this vacuole digestion takes place and the digested particles diffuse into the cytoplasm. The remaining undigested material is then moved to the surface of the cell and thrown out.
