Amoeba

An amoeba is a single-celled organism that lives in water or moist environments. It moves by extending parts of its cell membrane called pseudopodia (“false feet”) to slide along surfaces. Amoebas absorb nutrients by engulfing food particles through a process called phagocytosis. They are flexible, shapeless cells, capable of changing their form as needed. Amoebas are important in ecosystems as decomposers and are also studied in biology for understanding cell behavior and movement. Despite their simplicity, they are complex in how they adapt, feed, and reproduce within their environment.
