Amoeba envelops their food through endocytosis or phagocytosis, where the flexibility of the plasma membrane creates pseudopodia.
- The pseudopodia are the temporary arm-like projection in the amoeba that helps collect nutrition, alter its size and shape, and act as a locomotion organ.
Amoeba takes in food using temporary finger-like extensions of the cell surface, which fuse over the food particle forming a food vacuole. Inside the food vacuole, complex substances are broken down into simpler ones, diffusing into the cytoplasm. The remaining undigested material is moved to the surface of the cell and thrown out. The complete phagocytosis process includes intake, digestion, absorption, assimilation, and egestion process.
