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 ...

Pseudopods have two main functions: (1) locomotion and (2) capture of prey or engulfing of food. For instance, amoeba can crawl by extending the cytoplasm and the contraction of the filaments.
