=What Do Rod Cells Do?=

Rod cells help detect dark and light. They work like when you wake up in the middle of the night and you walk into light. It’s so bright that you feel like you’re staring at the sun but your Rod cells just need to adjust to the light. Then when you walk back into the dark, it’s so dark because your Rod cells need to adjust back to the dark =Where Are Rod Cells Located In The Eye?=

Rod cells are located in the Retina of the eye. The Retina contains of 120 million rod cells and 7 million cone cells- in each eye. Rod cells can't tell the difference between colors. They can see in black white and shades of gray.

=What Are The Special Parts Of A Rod Cell?=

Mitochondria- The Mitochondria is the part of the eye that holds most of the rod cells energy. Inner And Outer Segment- The Inner and Outer Segment is the specialized part of the cell full of Mitochondria. Outer Limiting Membrane- The Outer Limiting Membrane is the boundary between the Retina and the Vitreous body. Membrane Disks- The Membrane disks are the thin limiting covering of a cell or a cell part. Rhodopsin- The rhodopsin is the bright photosensitive pigment.



=What Are The Differences Of A Rod And Cone Cell?= = = Rod cells see black, white, and shades of gray and tell us the form or shape that something has. Rods can't tell the difference between colors, but they are sensitive by allowing us to see when it's very dark. Cone cells sense color and they need more light than rod cells to work well. The retina contains three types of cones. Each cone type is sensitive to one of three different colors- red green or blue. =References=
