Final answer:
The type of neuronal cell that detects bright light and provides color vision is the cone. Rods are adapted for low-light conditions and cannot detect color, whereas cones are used for vision in bright light and can discern different colors.
Step-by-step explanation:
The type of neuronal cell that detects bright light and provides high-resolution color vision is the cone. The retina contains two major types of light-sensing cells known as photoreceptors: rods and cones. Rods are highly sensitive to light and well-suited for low-light conditions but do not provide color information; they are only capable of detecting shades of gray. On the other hand, cones are less sensitive to light but are responsible for detecting bright light and are crucial for high-resolution color vision. Cones are concentrated primarily in the fovea, which is the center of the retina and is the area required for detailed vision.
