Pseudopodia: Learn about pseudopods

Learn about pseudopods, temporary extensions of the cytoplasm used for locomotion and feeling by some single-celled and multicellular organisms. Discover the four types of pseudopods (lobopodia, axopodia, filopodia and reticulopodia) and their formation, structure and functions. Protozoan - Amoeba, Pseudopodia, Movement: The amoebae also are extremely diverse. Amoebae are defined based on pseudopodia type: those with thin, or filose, pseudopods, which may be reinforced by stiff microtubule proteins, are classified in the supergroup Rhizaria (e.g., foraminiferans and radiolarians), whereas those with lobose pseudopods, which are blunt and are not reinforced, are classified in the supergroup Amoebozoa. Both groups of amoebae can be “naked” or housed inside a shell ... Learn how cells use pseudopodia, or false feet, to move across surfaces and through mediums. Explore the process, mechanisms, and structures of pseudopodial locomotion in different organisms and cells. Morphologically, pseudopodia can be assigned to one of four types: filopodia, lobopodia, rhizopodia, and axopodia. Lobopodia (Fig. 3.8), the most common form among parasitic amoebae, are blunt and may be composed of both ectoplasm and endoplasm or of ectoplasm only. In most species, lobopodia form slowly. Observation of living specimens clearly shows the gradual flow of granular endoplasm, when present, into the broad projection. Entamoeba histolytica, an important parasite of the human ...
