Answer:
The center of the retina is a pit called the fovea centralis The cells that are photoreceptors (detect color) are cones
In low light conditions, only rods are activated, and visual acuity is best in the Corners(as peripheral vision)of the eye.
In bright light conditions, visual acuity is best when light is focused on the center of the macula of the eye.
A single ganglion cell outside of the fovea receives input from _Multiple rod(s). Each cone synapses with one ganglion cell(s).
