Cone cells

• detect colour
• sensitive to high light intensities
• contain iodopsin - light sensitive pigment
• better visual acuity (sharpness)

Rod cells

• black and white images
• rhodopsin -light sensitive pigment
• sensitive to low light intensities

Bipolar cells

• connect photoreceptor cells to ganglion cells
• rod cells share a single bipolar cell
• cone cells connected to its own bipolar cell

Ganglion cells

• nerve…
