Summary Introduction
To draw: The graph depicting the distribution of rods and cones in the retina.
Concept introduction: A typical retina of a mammal contains two types of photoreceptors, the rods and the cones. The rods are present in larger number than cones. There are 125 million rods and 6 million cones in a typical retina. The cones of the retina mediate color vision while the rods mediate vision during night.

Get any one Large leaf that serves as specimen.
Make a drawing of the leaf that is half its actual size. For example, if the leaf is 20 cm long
and 10 cm wide, then your drawing must be 10 cm long and 5 cm wide and the magnification
0.5 or % the original size. Your drawing must be accurate. Measure the length and width of your leaf with a ruler and divide each measurement by 2 before you make your drawing.
A typical incandescent lightbulb emits approximately 3 x 1018 visible-light photons per second. Your eye, when it is fully dark adapted, can barely see the light from an incandescent lightbulb 10 km away. How many photons per second are incident at the image point on your retina? The diameter of a dark-adapted pupil is 6 mm.
