Root Explanation

Photoperiodism → It is formed from "photo-" (from Greek "phōs", meaning light) and "periodos" (from Greek, meaning a cycle or period). The term refers to the physiological reaction of organisms to the length of day or night, specifically how light influences biological processes.

Memory Tip

Think of 'light' ('photo-') affecting a 'cycle' ('periodos') — this helps you remember that photoperiodism is about how light influences the timing of biological activities.
