We see colour with the help of _______cells while vision in dim light depends on __________cells of the retina.

Answer

**Step-by-Step Solution:**

1. **Identify the Function of Photoreceptor Cells**: The retina contains two main types of photoreceptor cells: cone cells and rod cells. Each type has a specific function related to vision.

2. **Cone Cells and Color Vision**: Cone cells are responsible for color vision. They contain light-sensitive pigments that allow us to perceive colors. There are three types of cone cells, each sensitive to different wavelengths of light (red, green, and blue).

3. **Rod Cells and Dim Light Vision**: Rod cells are responsible for vision in dim light conditions. They are more sensitive to light than cone cells and allow us to see in low-light environments. Rod cells do not detect color but are crucial for peripheral vision and motion detection.

4. **Conclusion**: Based on the functions of these cells, we can fill in the blanks in the question: "We see color with the help of **cone** cells while vision in dim light depends on **rod** cells of the retina."

**Final Answer**: We see color with the help of **cone** cells while vision in dim light depends on **rod** cells of the retina.
