Root Explanation

Photoreceptor → It is formed from "photo-" (from Greek "phōs", meaning light) and "receptor" (from Latin "recipere", meaning to receive). The word describes a cell or structure that receives or responds to light.

Memory Tip

Think of 'light' ('photo-') being 'received' ('receptor') by a cell — that's what a photoreceptor does.
