A pseudopod or pseudopodium (pl.: pseudopods or pseudopodia) is a temporary arm-like projection of a eukaryotic cell membrane that is emerged in the direction of movement. Filled with cytoplasm , pseudopodia primarily consist of actin filaments and may also contain microtubules and intermediate filaments .
Filose, meaning their pseudopods develop as filopodia. For example: Euglyphids, filose amoebae with shells of siliceous scales or plates, which are commonly found in soils, nutrient-rich waters, and on aquatic plants. Gromia, a shelled amoeba. Tectofilosids, filose amoebae that produce organic shells. Cercomonads, common soil-dwelling ...
Pseudopods (Greek for false feet) are lobe-like appendages which amoebas use to anchor to a solid surface and pull themselves forward. They can change their shape by extending and retracting these pseudopods. [14] Amoeba: Found in every major protist lineage. Amoeboid cells occur among the protozoans, but also in the algae and the fungi. [15 ...
Amoebozoa is a major taxonomic group containing about 2,400 described species of amoeboid protists, [8] often possessing blunt, fingerlike, lobose pseudopods and tubular mitochondrial cristae. [ 7 ] [ 9 ] In traditional classification schemes, Amoebozoa is usually ranked as a phylum within either the kingdom Protista [ 10 ] or the kingdom ...
Some examples of organisms that exhibit this type of locomotion are amoebae (such as Amoeba proteus and Naegleria gruberi, [2]) and slime molds, as well as some cells in humans such as leukocytes. Sarcomas , or cancers arising from connective tissue cells, are particularly adept at amoeboid movement, thus leading to their high rate of metastasis .
Most lobosans possess broad, bluntly rounded pseudopods, although one genus in the group, the recently discovered Sapocribrum, has slender and threadlike (filose) pseudopodia. [1] In current classification schemes, Lobosa is a subphylum, composed mainly of amoebae that have lobose pseudopods but lack cilia or flagella. [2] [3]
Cercozoa – various amoebae and flagellates, usually with filose pseudopods and common in soil; Foraminifera – amoeboids with reticulose pseudopods, common as marine benthos; Radiolaria – amoeboids with axopods, common as marine plankton; A few other groups may be included in the Cercozoa, but some trees appear closer to the Foraminifera.
Pseudopods (Greek for false feet) are lobe-like appendages which amoebas use to anchor to a solid surface and pull themselves forward. They can change their shape by extending and retracting these pseudopods. [43] Amoeba: Found in every major protist lineage.
