The process by which living organisms detect and respond to light, important for vision in animals and growth in plants.
Photoreception is essential for many animals to navigate their environment and for plants to grow towards sunlight.
Photoreception → It is formed from "photo-" (from Greek "phōs", meaning light) and "reception" (from Latin "receptio", meaning to receive). The word describes the process of receiving or detecting light.
Think of 'light' ('photo-') being 'received' ('reception') — that's what photoreception means.
