偽足是一些原生動物運動和取食的一種細胞器,是由於原生質層的流動,使身體表面生出無定形的指狀、葉狀或針狀的突起。

偽足根據形態和功能大致可分成4類:葉片偽足絲狀偽足根狀偽足和軸偽足,除原生動物外,其它無脊椎動物的變形細胞及高等動物的白細胞和吞噬細胞等亦可伸出偽足。[1]

A number of protozoan movement and feeding of a cellular device, made by some prominent cytoplasmic temporarily. Pseudopodium can be broadly divided into four categories. (1) leaves pseudopods, showing finger or tongue, and sometimes branch, but the end of the round. extended pseudopodia, the cells of the outer quality of the first prominent, followed by endoplasmic flow. (2) filopodia, and nearly all of the outstanding quality of extracellular, pseudopodia showed filamentous or branch. (3) root-like pseudopodia , showed filamentous pseudopods and interconnected to form a network, only the predation function, not used as campaign organ. (4) axis pseudopod, pseudopodium was needle-like, containing a number of micro-tubes from the axis wire. pseudopod axis Chang to a more fixed structure. In addition to protozoa, other invertebrates, the deformation of cells and higher animals such as white blood cells and phagocytic cells can also be extended pseudopod.
