Human rods and cones are homologous to the ragworm's ciliary photoreceptor cells.What is the difference between a human cone cell and a ragworm ciliary cell?

Question

Quizplus · Accepted Answer

The major difference between a human cone cell and a ragworm ciliary cell is their contribution to vision. Human cone cells, which are located in the retina of the eye, contribute to color vision and high-acuity vision in bright light. Ragworm ciliary cells, located in the eyespots along the body of the worm, are responsible for detecting light and dark, but not for color vision or high-acuity vision. Both types of cells contain photoreceptor pigments that respond to light, but they are specialized for different functions.
