Q How does the amoeboid movement occur and what are examples of beings and cells that use such movements for locomotion?

Amoeboid movements are created by cytoplasmic movements and plasma membrane projections known as pseudopods. Their formation actively changes the exterior shape of some portions of the cell surface making it move along a substratum. Pseudopods appear from differences of viscosity amongst neighboring regions of cytoplasm near the plasma membrane and from the contractile action of microfilaments.

Amoeboid movements take place, for instance, in amoebas a protozoan, organisms that use their movement to find food. The leukocytes, cells of the immune system, when attracted by chemical substances immune mediators use amoeboid movements to get out from capillaries in regions of tissue harm to participate in the inflammatory process.
