Noun: 1. The process by which a living cell ceases to function and is broken down: In biology and physiology, "cell death" refers to the natural, programmed, or pathological termination of a cell's life. It is a fundamental process in the development, maintenance, and health of multicellular organisms.

Usage

• "Cell death" is a standard, uncountable noun used in biological and medical contexts.
