Root Explanation

Celloidin is derived from "cell" (from Latin "cella", meaning a small room or chamber) and "-oidin" (a suffix used in chemistry to denote a substance resembling or derived from another). The word "celloidin" refers to a substance that resembles or is derived from cellulose, often used in histology and microscopy.

Memory Tip

Think of 'cell' as a small room or chamber, and '-oidin' indicating something that resembles it — this helps you remember that 'celloidin' is a substance related to cellulose.
