Cones are responsible for day vision, color vision, and visual acuity. A photoreceptor includes an inner segment (IS) and an outer segment (OS). The photoreceptor IS, as the main site of the mitochondria, is the photoreceptor’s metabolic center. The photoreceptor’s OS is made up of disc...
The cones are responsible for sharp color vision in daylight. The rods provide vision in dim light. Near the center of the retina is a small depression about 0.3 mm in diameter which is called the fovea. It consists entirely of cones packed closely together. Each cone is about 0.002 mm (...
Many transduction proteins have different isoforms in rods and cones, and others are expressed at different levels. Moreover rods and cones have a different anatomy, with only rods containing membranous discs enclosed by the plasma membrane. These differences must be responsible for the difference in...
- elements composing the layer of rods and cones (Jacob's membrane) in the retina of the eye are of two kinds, rod cells and cone cells, the former being much...- comprising two types of photoreceptor cells. Rods are primarily responsible for dim-light scotopic vision and cones are ...

Most likely, this is a "perfect storm" scenario and all of the above reasons are somewhat responsible for this year's pine cone boom. Whatever the reason, if you live in New York and have lots of pine trees in your yard, it's going to be an especially busy (and sticky) spring for...
human eye because of the two types of photoreceptor cells - rods and cones - located in the retina of the eye. Rods are sensitive to light and dark; cones are sensitive to red, green & blue light and responsible for color vision. These photoreceptors convey the color of light to our ...

Physiology One of the photoreceptors in the retina of the eye that is responsible for daylight and color vision. These photoreceptors are most densely concentrated in the fovea centralis, creating the area of greatest visual acuity. Also called cone cell. The American Heritage® Medical Dictionary...
