Section APaper 2: Labeling & Identification (5 Questions)
Identify the structures in the Bio-Realistic Eye Cross-Section diagram above.
Which structure in the eye is responsible for refracting (bending) light as it enters the eye?
Identify the part of the eye that contains light receptor cells, some sensitive to different colors.
Which structure carries electrical impulses from the eye to the brain?
The hole in the center of the iris through which light enters the eye is called the:
Section BPaper 4: Definitions & Functions (5 Questions)
Define the term "sense organ".
Describe the function of the cornea.
Describe the function of the iris.
Describe the function of the lens.
Describe the function of the retina.
Section CPaper 6: Location & Experimental Design (5 Questions)
Where is the blind spot located in the eye?
Explain why the blind spot is called "blind".
A student is designing an investigation to find the blind spot. Which variable should they keep constant?
In an investigation, a student found their blind spot at 15 cm from their eye. Identify the dependent variable in this investigation.
State one safety precaution when conducting an eye anatomy investigation in a laboratory.
Examiner Guidance
Precision Matters: Use exact anatomical terms (e.g., "Optic Nerve" not "Brain Nerve", "Retina" not "Back of eye").
Function Linking: Always link structure to function (e.g., "Cornea refracts light", not just "Cornea is transparent").
Common Mistakes: Do not confuse cornea and lens (both refract, but cornea does most initial bending). Blind spot has no receptors because optic nerve exits there.
