"Amoebe is an organism which has the ability to alter its shape, primarily by extending and retracting pseudopods."(wikipedia) | |||
"Amoebae move and feed by using pseudopods, which are bulges of cytoplasm formed by the coordinated action of actin microfilaments pushing out the plasma membrane that surrounds the cell. Typically, an amoeba moves by extending a pseudopod, attaching it to the substrate and filling it with cytosol, then releasing its rear portion from attachment to the substrate, which results in the organism being propelled forward."(wikipedia) | |||
"A pseudopod or pseudopodium (plural: pseudopods or pseudopodia) (from the Greek word ψευδοποδός, ψευδός "false" + ποδός "foot") is a temporary cytoplasm-filled projection of a eukaryotic cell membrane or a unicellular protist. Pseudopods may be used for motility, or for ingesting nutrients or other particulate matter."(wikipedia) | |||
