Amoeboid movement

This is the type of movement that can be observed in some protozoans such as Amoeba and some mammalian white blood cells. When Amoeba moves toward a certain direction, the cytoplasm extends by flowing into that direction as seen in Figure 2.3. By doing so, it extends and forms a projection called pseudopodium (false feet). Further extension of pseudopodium in the same direction causes more cytoplasm to move to it. As the result, Amoeba moves from one place to another. White blood cells also move in the same way in engulfing pathogens
