In the Human Retina

Question

In the human retina,
A)cone cells can detect colour, but rod cells cannot.
B)cone cells are more sensitive than rod cells to light.
C)cone cells, but not rod cells, have a visual pigment.
D)rod cells are most highly concentrated in the centre of the retina.
E)rod cells require higher illumination for stimulation than do cone cells.

Accepted Answer

Cone cells contain photopigments that allow them to detect different wavelengths of light, which our brains interpret as different colors. Rod cells, on the other hand, contain only one type of photopigment and are more sensitive to low levels of light, but cannot distinguish between different colors.
