photoreceptors
A specialized area of sensory neuron that detects a specific stimulus is called a sensory receptor. These receptors are designed to respond to specific forms of stimulation, such as touch, light, or sound, and convert the energy from these stimuli into electrical signals that the nervous system can interpret.
Sensory neurons, also known as afferent neurons, carry information from sensory receptors to the central nervous system (CNS). These neurons transmit information about external stimuli (such as touch, sound, and light) or internal conditions (such as pain or temperature) to the brain and spinal cord.
A reflex is an automatic response, that protects the organism from a harmful stimulus. The receptors detect a stimulus which generates a nerve impulse along the sensory neurone to the Central Nervous System (CNS). The CNS decides the appropiate response to the stimulus. The nerve impulse then travels across a synapse to the relay neurone, across another synapse to the motor neurone to the effector. This is normally a muscle or an organ which moves or responds to bring about a response appropiate to the stimulus.
The message is transferred with an electron signal, pulses (arcing between the two neurons). This is similar to an electrical circuit (in which electrons also flow to different circuit components), or to a fiber optic line (where pulses of light serve as substitutes to the electrons).
YES. Plants absorb AND reflect green light. Leaves are green due to a compound called chlorophyll. The light absorbed by chlorophyll is used to power photosynthesis, the conversion of light energy into chemical energy. On a relative basis, chlorophyll absorbs more blue and red light, compared to green light; and therefore reflects less red and blue light. As a result, there is more green light than red or blue light reflected, so the chlorophyll containing part of the plant appears green. It is commonly thought that chlorophyll does not absorb green light, but that is a fallacy. A dark green leaf can absorb 90% of the green light impinging on it. In contrast, 95% of the red and blue light may be absorbed.

Sensory (afferent) neurons
The message is transferred with an electron signal, pulses (arcing between the two neurons). This is similar to an electrical circuit (in which electrons also flow to different circuit components), or to a fiber optic line (where pulses of light serve as substitutes to the electrons).
The nerve cells connected in the eyes, nose, skin, and tongue are called sensory neurons. These specialized cells are responsible for detecting and transmitting sensory information from these organs to the brain for processing. Each type of sensory neuron is tuned to respond to specific types of stimuli, such as light (in the eyes), odors (in the nose), touch (in the skin), and taste (in the tongue).
You get light green.
No. Color is a sensory perception of the various wavelengths of light.

The fans at the concert were almost louder than the music, and the light show was stunning. The whole experience was sensory overload. Sensory is an adjective.
Because a green light has a light bulb behind green plastic.
