Caption: False-colour scanning electron micrograph (SEM) of rod cells situated in the human retina. Two layers are visible here : one at top (pinkish) which has been severed while in the one below rods are still connected to their nuclei visible as soft purple spheres. About 130 million rod cells are situated in a retina and together with the cones (about 6.5 million and not visible here) represent the photosensitive cells in our eyes. Rod cells are considered to be receptors for night vision whereas cones are for daylight and colour vision. Magnification: x1450 at 6x7cm size.
