Eyes, Rod and Cones

What is the function of the cornea in the eye?

• To detect color and detail in the visual field.

• To produce tears for lubrication.

• To focus light into the eye.

• To regulate the amount of light entering the eye.

What is the role of the retina in the eye?

• It is responsible for controlling the size of the pupil.

• It contains light-sensitive cells that convert light into electrical signals.

• It helps in focusing the light onto the retina.

• It produces tears to keep the eye moist.

What special cells that are inside the retina?

• cones

• rods

• rods and cone

• optic nerves

What is the main function of rod cells in the eye?

• Regulating the amount of light entering the eye

• Vision in low light conditions and peripheral vision

• Producing tears to keep the eye moist

• Color vision and central vision

How do rod cells help in low light conditions?

• They have no function in low light conditions.

• They are responsible for color vision in low light conditions.

• They are sensitive to bright light and help in day vision.

• They are sensitive to low light and help in night vision.

What is the main function of cone cells in the eye?

• Detecting sound waves

• Regulating body temperature

• Producing tears

• Color vision and detecting fine details

How do cone cells help in color vision?

• By detecting different wavelengths of light

• By controlling the movement of the eye

• By producing tears to keep the eye moist

• By helping to detect sound waves

What is the main difference between rod and cone cells in the eye?

• Rods are for low light, cones are for color and detail in bright light

• Rods and cones have the same function in the eye

• Rods are only found in the center of the retina, cones are found throughout the retina

• Rods are for color vision, cones are for low light

What colors do the rods see?

• black, white and gray

• colorful colors

• only white

• only black and gray

How do rod and cone cells work together to help us see in different lighting conditions?

• Rods and cones work independently and do not contribute to our ability to see in different lighting conditions.

• Rods and cones have no role in helping us see in different lighting conditions.

• Rods help us see in low light conditions, while cones help us see in bright light conditions and perceive color.

• Rods help us see in bright light conditions, while cones help us see in low light conditions and perceive color.
