How is the rod cell adapted?

Rod cells are specialized photoreceptor cells in the retina that are highly sensitive to light, allowing them to function in low-light conditions. They contain a high concentration of the photopigment rhodopsin, which enables them to detect dim light and contribute to night vision. Rod cells have a cylindrical shape that increases their surface area for capturing photons, and they are connected to multiple bipolar cells, enhancing their sensitivity by pooling signals from several rods.
