Here's a breakdown:

* Phagocytosis comes from the Greek words "phagein" (to eat) and "kytos" (cell).

* It's a process where a cell engulfs a particle (like a bacterium, a piece of debris, or even another cell) and encloses it in a membrane-bound vesicle.

* This vesicle then fuses with lysosomes, which contain enzymes that break down the engulfed material.

Other terms related to cell eating:

* Endocytosis: A general term for the process of a cell taking in substances. Phagocytosis is a type of endocytosis.

* Pinocytosis: A type of endocytosis where the cell takes in small droplets of fluid.
