There are to types of cells that act as photoreceptors in the eye. The Rod and Cones. Rods detect only the presence or absence of light withough distinguishing between colours thus giving black nad white vision (as at night). Cones detect coloured in the images but are less sensitive, ie they require more light to function.

An organ that contains light receptors?
Light receptors called rods and cones are found in the retina of the eye. Rods are resposible for discerning light as blackand white and the cones colour.
What organs are regarded as photoreceptors?
The eye ( retina) or any other receptors that respond to light.
The eye is considered part of what nervous system?
The retina is the part of the eye that contains light receptors.
Where are the light receptors located in the eye?
Light receptors are located in retina of eye ball. They are rods and cones. Rods are for night vision and cones for color vision. Retina is innermost layer in an eye in posterior compartment. Inside it, is vitreous gel. It is a part of brain and gets separate blood supply from branch of internal carotid artery. They are present in large number in fovea centralis. They are absent, where the optic nerve leaves the eye ball. That creates the 'blind spot' in visual area.
How does the human eye respond to energy?
We see out of the eye because of the light that's hits the eye and the light that we see it sends a signal to the brain and then we can see the picture.
What part of the eye contain the receptors?
The retina is the part of the eye that contains light receptors.
An organ that contains light receptors?
Light receptors called rods and cones are found in the retina of the eye. Rods are resposible for discerning light as blackand white and the cones colour.
What are the receptors in the eye?
You have rod cells and cone cells as receptors in your eye. Rods are for intensity of the light. Cone cells are for color vision.
What are light receptors?
Light receptors are found in the eye. There are two types of receptors; rods and cones. Rods produce the black and white pigments and the Cones produce the color pigments.
What is the specific job of a rod in your eye?
Rods are light-sensitive receptors in the retina of vertebrates.
What organs are regarded as photoreceptors?
The eye ( retina) or any other receptors that respond to light.
What does the cone in the eye do?
The cones in your eye are responsible for helping you to see color. They are in the retina and operate only in light. The rods are the other receptors.
What does the cone do in the eye?
The cones in your eye are responsible for helping you to see color. They are in the retina and operate only in light. The rods are the other receptors.
The inner black surface of eye is?
I believe you mean the "retina". It appears black when you look into your friend's eyes, but it really is red. It appears black because of the refraction of light. The eye is designed to take light in, not let it out. The retina is the lining in the back of the eye that contains the light receptors, and many blood vessels as well.
Do auditory receptors detect light?
No, auditory receptors do not detect light. Auditory receptors are sensory cells that respond to sound waves, which are pressure waves with frequencies between 16 hertz and 20,000 hertz. Light, on the other hand, is an electromagnetic wave with frequencies ranging from about 400 terahertz to 790 terahertz. Auditory receptors are located in the inner ear, in the basilar membrane of the organ of Corti, while light receptors are located in the retina of the eye. Therefore, auditory receptors and light receptors are different types of sensory cells that detect different types of stimuli.
What are cones and what is their role in the perception of color?
Cones are the light receptors on the retina of an eye that distinguish the various colors.
What are two classifications of sensory receptors?
There are many different sensory receptors, but olfactory receptors in the nose, and cones and rods in the eyes are two specific types of sensory receptors. Olfactory detects the chemical presence and your brain identifies it as a smell. The rods and cones of the eye process light and color to form images that your brain processes as vision.
