An amoeba is a shapeless blob of ''jelly'' that engulfs random objects on its way to know where in particular. Amoeba move by using their pseudopodium which is a "false leg." Amoeba can be harmful or helpful to man-kind and other living things. Amoebas are composed of just one cell. They are protozoans with no fixed shape. Most have no hard parts and look like blobs of jelly. However, some amoebas do build shells. Amoebas move by making part of its body move in the direction it wants to travel. Then slowly the rest of the cell follows. In order to eat an Amoeba flows around other microorganisms and then engulfs them. To reproduce the Amoeba splits itself into two cells.
