Question

What is the term used for the photoreceptor cells of the retina which is sensitive to color?

Answer 1

Retina:

1. The retina of the eye is a sensory membrane that lines the back of the eye and is responsible for sensing light and thereby creating signals that travel through the optic nerve to the brain.
2. The retina contains photoreceptor cells.
3. Photoreceptor cells come in two different varieties: rods and cones. The photopigments, a class of light-sensitive proteins, are present in these cells.

Cones:

1. Cones are the retina's color-sensitive photoreceptor cells.
2. Cones are involved in both color vision and daytime (photopic) vision.
3. There are three different types of cones in the human eye, each of which has unique photopigments that react to red, green, and blue light.
4. These cones' photopigments and diverse combinations of them result in the perception of distinct colors.
