A pseudopodium or pseudopod (plural: pseudopodia or pseudopods) is a temporary cytoplasmic extension of an amoeboid cell, used for locomotion and ingestion of food. The name means literally ‘false foot’. Pseudopodia are powered by microfilaments near the cellular membrane. About half of the internal space of an amoeba contains microfilaments. A pseudopodium contains both granuloplasm and hyaloplasm. Pseudopodia which only contain hyaloplasm are called subpseudopodia.
Form and structure of the pseudopodia are important taxonomical characters. Depending upon their shape, several types of pseudopodia are distinguished, e.g.:
