Question
Chapter 12, Problem 46CA
Summary Introduction
To explain:
The rod vision may be more important in dim light than in bright light.
Introduction:
The retina contains the photoreceptors that respond to the light. The photoreceptor of eye is modified into rods and cones cells. These are present in the deep layer of retina and associated with the epithelium layer of retinal pigment.
