Final answer:
A cup-shaped eye has improved discrimination in light direction and intensity over a flat sheet eye.
Step-by-step explanation:
A cup-shaped eye has improved discrimination in light direction and intensity over a flat sheet eye. This statement is true. Cup-shaped eyes, like those found in vertebrates including humans, have several advantages over flat sheet eyes found in invertebrates. The cup shape allows for the concentration of light onto the surface of the retina, leading to better detection of light direction and intensity. Additionally, cup-shaped eyes provide a better depth perception compared to flat sheet eyes.
