WebDec 24, 2024 · Pseudopodia function to trap and engulf food particles and to direct movement in rhizarian protists. These pseudopods project outward from anywhere on the cell surface and can anchor to a substrate. The protist then transports its cytoplasm into the pseudopod, thereby moving the entire cell. WebPseudopods mainly have two functions - engulfing of food (capture of prey) and locomotion. For example, the amoeba can creep by filament contraction and cytoplasm extension. While it goes onward, the pseudopod bulges away from the cell edge to engulf in a complete organism. Besides this, the pseudopods are also used in the process of ingestion ...

WebMay 28, 2024 · Some cells get around by pushing cytoplasm into an extension of the cell membrane, forming a structure called a pseudopod. This is true of Amoebas and white blood cells in our bloodstream. Pseudopods can be classified into several varieties according to the number of projections (monopodia and polypodia), and according to their appearance: Lamellipodia are broad and flat pseudopodia used in locomotion. They are supported by microfilaments which form at the leading edge, creating a mesh-like internal network.
