pseudopodium
Noun 1. A temporary, flexible extension of the cytoplasm of a cell (especially in certain protozoans and some white blood cells) used for movement, feeding, or sensing the environment. It is a flowing projection that can be extended and retracted, allowing the cell to change shape and move.
The term is used primarily in biology to describe a specific cellular structure. It is a formal, scientific term. * For movement (locomotion): The cell extends a pseudopodium in the desired direction, then flows its contents into it. * For feeding (phagocytosis): The cell extends pseudopodia to surround and engulf food particles or other matter.
- Noun:
- An amoeba moves by extending a pseudopodium and flowing into it.
- The white blood cell formed a pseudopodium to engulf the invading bacteria.
- The organism uses its pseudopodium not only for locomotion but also to capture food.
- Plural Form: The standard plural is pseudopodia. The form is also occasionally used but is less common in scientific literature.
- The cell extended multiple pseudopodia in different directions.
- Pseudopod (noun): A common, shortened form of "pseudopodium." It is widely used and often considered synonymous in general biology.
- The amoeba's pseudopod surrounded the food particle.
- Pseudopodal (adjective): Relating to or resembling a pseudopodium.

- False foot: A direct, descriptive translation of the word's Greek roots ( = false, = foot). This is a less technical synonym.
- Lobopodium (noun): A specific type of pseudopodium that is broad and blunt-ended, typical of amoebas.
The word "pseudopodium" has a single, specific meaning in cell biology. It does not have common idiomatic or metaphorical uses outside of this scientific context.

temporary outgrowth used by some microorganisms as an organ of feeding or locomotion
