The locomotory organ of Amoeba is pseudopodia or false feet. Pseudopodia are temporary structures that keep changing for the movement of Amoeba. The streaming of protoplasm in Amoeba is a simple form of movement that is facilitated by pseudopodia. Pseudopodial locomotion is a type of cellular movement used by certain eukaryotes, particularly slime molds and certain types of protozoans, such as amoebas.
