What do rod cells and cone cells do?

Answer 1

Rods respond to very low levels of light and are primarily responsible for night vision.

They also:

A Rod Cell is a type of light-sensitive nerve cell found in the retina.

Rod cells do not process fine details or colour differences but are highly sensitive to light. A single photon of light is all that is require to produce a response from a Rod Cell.

Loss Rod Cells can result in the condition known as Night Blindness.

Answer 2

Rods are light-sensitive receptors in the retina of vertebrates. They are sensitive to dim light. They contain a photo-sensitive pigment "rhodopsin" which when exposed to light absorbs it and the light energy released in this reaction causes a generator potential which if matches threshold stimulus travels through neurons as action potential into the optic nerve transmitting it to the brain.In the absence of light(darkeness) vitamin A and ATP converts it back into light sensitive pigment rhodopsin thus stopping the signals to brain via optic nerve.

Answer 3

There are two types of photoreceptors in the retina of the eye - rod and cone cells. Rod cells (containing the visual pigment rhodopsin) are used mainly in dark light, and it gives black and white vision only. Cone cells (containing the visual pigment iodopsin) are used in high light intensities, and gives colour vision.

Answer 4

Rod cells are specialized photoreceptor cells in the retina that are responsible for detecting dim light and shades of gray, allowing for night vision. Cone cells, on the other hand, are responsible for detecting colors and details in bright light conditions. Together, they help us perceive the visual world in varying light intensities and colors.

Answer 5

Rods see black and white, shadows, and highlights

Answer 6

vision in dim light
