Study Notes
Phagocytosis Overview
- Phagocytosis, meaning "cell eating," is a cellular process where cells engulf large particles or solids.
- The process begins with the cell membrane forming pseudopodia (false feet).
- These pseudopodia surround and enclose the particle.
- The enclosed material is then packaged into a membrane-bound vesicle called a phagosome.
- The phagosome fuses with lysosomes.
Lysosomes and Digestion
- Lysosomes contain digestive enzymes.
- The enzymes within lysosomes break down the ingested material.
Phagocytosis in Single-celled Organisms
- Some single-celled organisms use phagocytosis to ingest food.
Phagocytosis in Multicellular Organisms
- Multicellular organisms also utilize phagocytosis in specialized cells.
- White blood cells exhibit phagocytosis to engulf and destroy invading bacteria, viruses, or damaged cells, contributing to the body's defense.
- The process also removes cellular debris.

Description
Explore the fascinating process of phagocytosis, a vital cellular function sometimes referred to as 'cell eating'. This quiz covers how cells engulf particles, the role of lysosomes in digestion, and the significance of phagocytosis in both single-celled and multicellular organisms, particularly in immune response.
