Area of retina with only cones is called ………….. while area of retina with no photoreceptors is called ……………. .

Explanation

**Step-by-Step Solution:**

1. **Understanding the Retina**: The retina is a thin layer of tissue located at the back of the eye. Its primary function is to receive light and convert it into neural signals that the brain can interpret.

2. **Identifying Areas of the Retina**:
- The area of the retina that contains only cones is referred to as the **yellow spot** or **macula**. This region is crucial for high visual acuity and color vision, as cones are responsible for these functions.
- The area of the retina that has no photoreceptors is known as the **blind spot**. This region does not detect light because it lacks photoreceptors (rods and cones).
