Answer
Cones in the retina are responsive to red, green, and blue.
Solution
The correct answer to fill in the blank is "cones."
According to the trichromatic theory of color vision, cones in the retina are responsive to red, green, and blue light.
Here's a brief explanation of the options provided:
- **Rods**: These are photoreceptor cells in the retina that are more sensitive to light and are responsible for vision in low-light conditions, but they do not detect color.
- **Afterimages**: This term refers to the visual illusion that occurs when you look away from a bright stimulus and still see an image of it, but it is not related to the trichromatic theory.
- **Lenses**: These are optical devices that help focus light but are not involved in color detection in the retina.
Thus, the complete statement would be: "According to the trichromatic theory of color vision, cones in the retina are responsive to red, green, and blue."

Simplify this solution The Deep Dive
The trichromatic theory of color vision posits that our eyes have three types of cone cells in the retina, each sensitive to a different color spectrum: red, green, and blue. These cones work together to help us perceive a full range of colors through the combination of responses from these three types. In practical terms, this means that when you see a rainbow or the beautiful hues of a sunset, it’s your cone cells doing the heavy lifting! However, things can get tricky; for instance, when colors are perceived inaccurately (like in color blindness), it’s often due to one or more of these cone types being absent or malfunctioning.
