Answer:
Pseudopods
Step-by-step explanation:
Amoeba move by extending their cytoplasm to form pseudopods on the surface of mud or soil. The pseudopodia are formed by forward streaming of endoplasm forming a protuberance. The endoplasm then converts to ectoplasm which stiffens the pseudopodium. More cytoplasm flows into the pseudopodium with the result that the organism gains a new position.
