Usage: technical/scientific; commonly used in biology and neuroscience

Examples

• The photoreceptive cells in the retina convert light into electrical signals.
• Photoreceptive proteins in the eye enable us to see colors and shapes.
• Some organisms have photoreceptive structures that help them detect day and night cycles.
• The photoreceptive layer of the skin responds to ultraviolet radiation.
• Scientists study photoreceptive mechanisms to understand how vision works at the molecular level.
