伪足是一些原生动物运动和取食的一种细胞器，是由于原生质层的流动，使身体表面生出无定形的指状、叶状或针状的突起。
伪足根据形态和功能大致可分成４类：叶片伪足、丝状伪足、根状伪足和轴伪足，除原生动物外，其它无脊椎动物的变形细胞及高等动物的白细胞和吞噬细胞等亦可伸出伪足。[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.
一些 原生动物 运动和取食的一种 细胞器，由部分 细胞质暂时突出而成.伪足大致可分成４类.（１）叶片伪足，呈指状或舌状，有时分支，但末端圆形.伪足伸出时， 细胞的 外质先突出，随后内质流入.（２） 丝状伪足，几乎全为细胞外质的突出，伪足呈丝状或分支.（３） 根状伪足，伪足呈丝状并且互相连接成网，只有捕食功能，不用作运动器官.（４） 轴伪足，伪足呈针状，内有由若干 微管组成的 轴丝.轴伪足常为较固定的构造.除原生动物外，其它 无脊椎动物的变形细胞及 高等动物的[[]]白细胞和 吞噬细胞等亦可伸出伪足[2]
