Pseudopodia Explained

Pseudopodia are temporary, flexible, finger-like or foot-like extensions of a cell's cytoplasm. The term literally means "false feet".

Function of Pseudopodia

• Locomotion: Organisms use pseudopodia to move by extending the cytoplasm in the direction of movement and anchoring the cell body to the new position.
• Feeding: Pseudopodia are also used to surround and engulf food particles, a process called phagocytosis.

Pseudopodia in Organisms

These structures are most famously associated with single-celled organisms like Amoeba. Amoeba uses its pseudopodia for both movement and capturing food.

Comparison with Other Options

• Earthworms: Move using muscle contractions and bristles called setae.
• Paramecium: Moves using numerous short, hair-like cilia covering its surface.
• Hydra: Moves using tentacles and body contractions, often attaching and detaching its base.

Therefore, the finger-like extensions known as pseudopodia are characteristic features of Amoeba.
