SSS3 Biology: The Cell

The cell (from Latin cella, meaning "small room") is the basic structural, functional, and biological unit of all known organisms. Cells are the smallest units of life, and hence are often referred to as the "building blocks of life". The study of cells is called cell biology, cellular biology, or cytology.

Lesson summary
Overview
