Pseudopodia are temporary, foot-like extensions of the cell membrane and cytoplasm used by some eukaryotic cells for movement and feeding. Commonly found in amoebas, pseudopodia enable these cells to change shape and navigate their environments.
5 Must Know Facts For Your Next Test
Pseudopodia are primarily associated with amoeboid movement.
They play a crucial role in the process of phagocytosis, where the cell engulfs food particles or other cells.
The formation of pseudopodia is driven by the polymerization and depolymerization of actin filaments in the cytoskeleton.
Pseudopodia can be classified into different types such as lobopodia, filopodia, and reticulopodia based on their shape and structure.
Certain pathogenic eukaryotes like Entamoeba histolytica use pseudopodia for tissue invasion and causing disease.
