photoreceptor

/fˌoʊɾoʊɹᵻsˈɛptɚ/ noun

A specialized neuron or other structure able to detect and react to light.

Word Origin From Greek phōs 'light' and Latin capere 'to take' with re- 'back' — a photoreceptor is literally a 'light-taker-back,' a cell that captures light. The root cept- (from capere) is incredibly productive: receive, concept, accept, except, intercept, perceive. The PIE root *kap- 'to grasp' gives us capture, captive, capable. So a photoreceptor seizes light and converts it into signals.

noun A specialized neuron or other structure able to detect and react to light. countable

The human eye contains photoreceptors that convert light into neural signals.
