Rod cells vs Cone Cells
Similarities and Differences between Rod Cells and Cone Cells
Rod cells and Cone cells are the two types of photoreceptor cells found in the retina of eyes. These cells are capable of absorbing light and converting the light into signals that can trigger a change in the membrane potential, which results in visual phototransduction. In other words, these cells assist in vision in presence of light.
Rod cells: A type of photoreceptor cells in the eye found concentrated at the outer edges of the retina. Rod cells are responsible for vision in low light conditions.
Cone cells: The second type of photoreceptor cell in the eye concentrated in the fovea of the retina. Cone cells are responsible for the vision in bright light and colour vision.
The present post explains the similarities and differences between Rod cells and Cone cells with a comparison table.
Similarities between Rods and Cones
Ø Both rods and cones are photoreceptor cells of the eye.
Ø Both can absorb photon (light)
Ø Both cells possess photoreceptor proteins to absorb the photons (light).
Ø Both are modified nerve cells.
