pseudopodium, temporary or semipermanent extension of the cytoplasm, used in locomotion and feeding by all sarcodine protozoans (i.e., those with pseudopodia; see sarcodine) and some flagellate protozoans. Pseudopodia are formed by some cells of higher animals (e.g., white blood corpuscles) and by amoebas. During amoeboid feeding, pseudopodia either flow around and engulf prey or trap it in a fine, sticky mesh. 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 ... Pseudopodia are temporary projections that extend from the cell body of certain single-celled organisms. They serve for movement and food capture, and can change shape and direction as needed. Learn more about the types, formation, and examples of pseudopodia. Pseudopodia (sing: pseudopodium) are cytoplasmic projections that are found on the cell membranes of eukaryotic cells. The word pseudopodia is derived from pseudo meaning false and podia meaning feet. Below is a well-labelled diagram of an amoeba which shows the cytoplasmic projections of pseudopodia. Scroll down for more on pseudopodia. Features The arm-like temporary projections arising from the eukaryotic cell membrane in the direction of movement are referred to as pseudopodia. The ...
