Biology Quiz: Rods and Cone Cells

What are the cells called that do not distinguish between different wavelengths of light?

• Rods

• Cones

• Bipolar cells

• Sensory neurons

Which cells can detect light at very low light intensities?

• Cones

• Rods

• Bipolar cells

• Sensory neurons

What is the protein pigment inside rod cells called?

• Iodopsin

• Rhodopsin

• Cyanopsin

• Melanopsin

What is the concept called when multiple rod cells connect to one bipolar cell?

• Visual acuity

• Retinal convergence

• Temporal summation

• Spatial summation

Which type of cone cells is responsible for perceiving blue color?

• Red cones

• Green cones

• Yellow cones

• Blue cones

Why don't we see colors in the dark?

• Because there's not enough light energy to break down the iodopsin

• Because the brain cannot process colors in the dark

• Because there's too much light energy to break down the iodopsin

• Because the cone cells are not functioning

What is the advantage of having only one cone cell connected to one bipolar cell?

• Low visual acuity

• High visual acuity

• Poor color perception

• Inability to distinguish separate light sources

Where in the retina do we find the highest number of cone cells?

• Optic nerve

• Peripheral retina

• Fovea

• Blind spot

What is the part of the retina that has no rod cells and no cone cells?

• Optic nerve

• Blind spot

• Peripheral retina

• Fovea

What is the advantage of rod cells?

• Provide low visual acuity

• Detect colors

• Trigger high visual acuity

• Absorb light at very low intensities
