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.
- The cell exhibited pseudopodal activity.
- 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
