Rod cells do not detect color. They are responsible for detecting low levels of light and are more sensitive to brightness and contrast rather than color. Cone cells, on the other hand, are responsible for detecting color.
The primary stimulus that informs the biological clock is light. Light is detected by specialized cells in the retina of the eye, which then send signals to the suprachiasmatic nucleus in the brain to regulate the body's circadian rhythm.
The retina, located at the back of the eye, is the part responsible for recording images. It contains cells called photoreceptors that detect light and convert it into electrical signals that are sent to the brain for processing.
The ear is the structure that detects sound. It consists of three main parts: the outer ear, the middle ear, and the inner ear. Sound waves enter the ear through the outer ear, travel through the middle ear, and are converted into nerve signals in the inner ear for the brain to process.
Visible light is a form of electromagnetic radiation that is visible to the human eye. It encompasses wavelengths from approximately 400 to 700 nanometers. Humans can detect this portion of the electromagnetic spectrum through the specialized cells in our eyes known as cones.
A stimulus is a DETECTECTABLE change in the environment. e.g. light is a stimulus to an animal or plant if it can detect the light with a sensing eye or chemical
Photoreceptors detect visual stimuli, specifically light. They are cells in the retina of the eye that are sensitive to different wavelengths of light and help to initiate the process of vision.
The eye .In there eye there is rod cells and cone cells. Rod cells detect color and Cone cells detect black and white. The cone cells let you see in the dark.
Light
Rods
There are certain cells in your eye retina that detect colour, called cone cells.
The cones, located in the retina, detect color.
rod and cone cells
Rods are for seeing light and dark, cones are for seeing color.
Rods are for seeing light and dark, cones are for seeing color.
I'm not sure if it's an organ but it's a reflex arc as it acts towards stimulus's (Change in environment) very quickly and the eye also contains receptor cells (Which tell the brain there is a stimulus) All this is learnt from my GCSE Biology classes Further reference - Ed excel text book.
