certain types of color receptor cells, called cones.
The blind spot does not have or serve a function. The blind spot is cause by a lack of receptors in the location where a person's optic nerve and blood vessels leave the eye.
Dogs are not capable of seeing colour. There are cells in the retina called 'cones' that aid in the perception of light. Dogs lack these type of cells and hence are incapable of seeing the world in colour, unlike humans
Blind people can "see" with their ears by relying on them to fill in the gaps caused by their lack of visual perception.

prokaryotic cells
The two organelles that plant cells have that animal cells lack are: 1. Cell wall 2. Vacuole.
This is a biology question, but the answer is Prokaryotic. ------------------------------------------------------------------------------------ Red blood cells also lack a nucleus.
