Pseudopodia, also known as pseudopods, are temporary cytoplasmic projections or "false feet" used for locomotion and engulfing food in some unicellularorganisms, such as amoebas and some white blood cells. The term "pseudopodia" comes from the Greek words "pseudes" meaning false, and "pous" meaning foot.
Structure of Pseudopodia
Pseudopodia are formed by the extension of the cytoplasm, supported by microfilaments of actin. The extension is driven by the assembly of actin filaments at the leading edge of the pseudopod, and the subsequent disassembly of filaments at the rear, allowing the cell to move forward.
