Petra walks into a brightly lit psychology lab to participate in an experiment involving the ability to perceive the colors of the rainbow. which photoreceptors will be most useful during this experiment?
a) conesb) foveac) lensd) rods

Cones  

Explanation:

Cones are the vision cells in the eye. These cells are found in the central part of the eye. These cells are mostly found in the fovea. Cones are in cylindrical shapes. These cells are responsible for color vision. These cells are found in three shapes

The S cells called small cells

The M cells called medium cells  

The L cells called large cells.  

These are also called the photo-receptors cells that are found in vertebrates. These cells have different capacities for different wavelength cells. These cells are responsible for color cells so these cells perform better in light.
