Describe the differences between the two photoreceptors, noting differences where you can.
There are two types of photoreceptors mentioned in your textbook and outline. Describe the
differences between these photoreceptors, noting differences where you can.
Solution
COLOR VISION-RODS-The rods are most sensitive to light and dark changes, shape and
movement and contain only one type of light-sensitive pigment. Rods are not good for color
vision.CONS-The \"blue\" cones have the highest sensitivity and are mostly found outside the
fovea, leading to some distinctions in the eye\'s blue perception.
WHAT ROLE DO THE RODS PLAY WHEN YOUR EYES ADAPT TO DARKNESS?RODS-
Rods work in low light conditions to help night vision.CONS-cones work in daylight and are
responsible for colour discrimination.
ARE THERE MORE OR LESS PHOTO RECEPTOR? RODS-The rods are more numerous,120
million.CONS-6 to 7 million
WHERE ARE THERE MORE OF THESE ON RETINA? RODS- rods are found everywhere in
the retina, except in and near the fovea.CONES-The green and red cones are concentrated in the
fovea centralis . The \"blue\" cones have the highest sensitivity and are mostly found outside the
fovea, leading to some distinctions in the eye\'s blue perception..
