Pseudopods The amoebas characteristic pseudopods false feet are extensions of its cytoplasm constantly changing shape and form These fluid dynamic protrusions allow 4 for targeted engulfment They are not simply random movements they are guided by chemical signals and visual cues from the particle The amoeba identifies a particle likely a bacterium or other small organic debris via chemotaxis following a chemical gradient or more rudimentary visual cues A key protein involved in the process is actinin Engulfment and Vesicle Formation Once the pseudopods have successfully encircled the food particle they fuse together creating a membranebound vesicle called a phagosome This encapsulates the particle within the amoebas interior This encapsulation is critical it isolates the particle preventing it from causing harm or disrupting the cells internal environment Digestion within the Phagosome The phagosome then merges with a lysosome a specialized organelle containing digestive enzymes These enzymes break down the captured food particle into its component molecules The nutrients are then absorbed into the cytoplasm of the amoeba supplying it with energy and essential
