How does an ameba move

Amoebae use pseudopodia (meaning "false feet") to move.

Explanation:

In the case of an amoeba moving, it's cytoplasm flows forward to form a pseudopodium, then it evens back out. In order to eat, it will form two pseudopodia and wrap those around to meet each other, enclosing its food, then the cytoplasm evens out again.
