Chapter 40, Problem 4FIB
Summary Introduction
Introduction:
The eye is a sensitive sense organ, which provides vision. It consists of photoreceptor cells, rods and cones, which are responsible for image formation during night and day. The eye contains various structures like; aqueous humor, vitreous humor, retina, iris, pupil, and so on.

- Figure 36.18 Which of the following statements about the human eye is false? Rods detect color, while cones detect only shades of gray. When light enters the retina, it passes the ganglion cells and bipolar cells before reaching photoreceptors at the rear of the eye. The iris adjusts the amount of light coming into the eye. The cornea is a protective layer on the front of the eye.arrow_forwardRods differ from cones in the following ways: a. They detect dim light, not bright light. b. They have a different visual pigment. c. They are not located in the retina. d.
