Phagocytosis is specifically achieved by which structure?

Phagocytosis, the process of engulfing particles or other cells, is primarily accomplished by the pseudopodium. This structure extends from the cell body and allows the cell to surround and ingest foreign material, such as bacteria or dead cells. During phagocytosis, the pseudopodia reach out and create a pocket around the target, which then eventually closes off, forming a vesicle that contains the engulfed substance.

The pseudopodium is crucial for this process as it exhibits the necessary adaptability and movement required to effectively capture and internalize particles. This active engagement with the environment distinguishes it from other cellular structures that may serve different functions in a cell, thus highlighting its role in phagocytosis specifically.
