Root Explanation

Bioluminescence is formed from "bio-" (from Greek "bios", meaning life) and "luminescence" (from Latin "luminescentia", meaning light). The word describes the phenomenon of living organisms producing light.

Memory Tip

Think of 'life' ('bio-') creating 'light' ('luminescence') — that's what bioluminescence means.
