Iodopsin is visual pigment of…………….. while rhodopsin is visual pigment of …………….. .

Explanation

**Step-by-Step Solution:**

1. **Identify the Visual Pigments**: The question asks for the visual pigments associated with two types of photoreceptor cells in the retina: iodopsin and rhodopsin.

2. **Define Rhodopsin**: Rhodopsin is a visual pigment found in the photoreceptor cells known as rods. Rods are responsible for vision in low light conditions (scotopic vision).

3. **Define Iodopsin**: Iodopsin is the visual pigment found in the photoreceptor cells known as cones. Cones are responsible for color vision and function best in bright light conditions (photopic vision).
