| 31. | Eventually, loss of rod cells leads to loss of cone cells ( cone photoreceptors ), the mainstay of human vision.
|
| 32. | Rod cells also respond slower to light than cones and the stimuli they receive are added over roughly 100 milliseconds.
|
| 33. | In vertebrates with three types of cone cells, at low light intensities the rod cells may contribute to color vision.
|
| 34. | A dorsal ocellus consists of a lens element ( cornea ) and a layer of photoreceptors ( rod cells ).
|
| 35. | This caused a considerable preservation in cone cell amount and function at P50, and a modest rod cell amount at P30.
|
| 36. | Since cone cells make color vision possible, the high prevalence of rod cells in lemur eyes suggest they have not dichromats.
|
| 37. | In rod cells the opsin molecules are embedded in the membranes of the disks which are entirely inside of the cell.
|
| 38. | Since cone cells are not as sensitive to dim light as rod cells, most night vision is limited to rod cells.
|
| 39. | Nocturnal lemurs such as mouse lemurs and dwarf lemurs, on the other hand, have retinas made up entirely of rod cells.
|
| 40. | Since cone cells are not as sensitive to dim light as rod cells, most night vision is limited to rod cells.
