Question

Which of the following is true about the difference between the rods and the cones?​ ​The rods are packed in an area called the fovea, and the cones are found more in the peripheral retina. ​The only difference between the rods and the cones is physical shape. ​There are about 120 million rods in the human eye and about 6 million cones. ​The rods control vision in high illumination conditions, and the cones control vision in low illumination conditions.

Answer 1

Answer: There are about 120 million rods in the human eye and about 6 million cones.

Explanation:

The retina of the eye consists of two photoreceptors which are called as rods and cones. The rods are numerous and are about 120 millions in numbers, these are more sensitive then the cones. The rods are sensitive to the light intensity but are less sensitive to the color.

There are about 6 million cones in the eye and these provides sensitivity towards the detection of color. These are more concentrated in the spot which is called as the macula.
