Compared to the rods, the cones in the retina are
A) more sensitive to very dim light.
B) more common toward the fovea.
C) less sensitive to detail.
D) less important for color vision.
Cones
Cells in the retina known as photoreceptors are crucial for seeing colors and operate optimally under well-lit conditions.
Rods
Photoreceptor cells in the retina of the eye that are highly sensitive to low levels of light and are primarily responsible for night vision.
Fovea
A tiny pit located in the macula of the retina that provides the clearest vision of all by having a high concentration of cones and no rods.
- Become familiar with the unique structural characteristics and functions of rods and cones in the human retina.
- Set apart the physiological bases for perceiving colors and for seeing in low-light environments.

Final Answer :
B
Explanation :
Cones are more densely packed towards the fovea, which is responsible for detailed vision. Rods, on the other hand, are more densely located away from the fovea and are more sensitive to dim light. Cones are also important for color vision.
