Photoreceptor cells and light-sensitive cells are not the same thing. Photoreceptor cells are a specific type of light-sensitive cell found in the retina of the eye that are responsible for detecting light and converting it into electrical signals that can be interpreted by the brain. Light-sensitive cells, on the other hand, refer to any cell in the body that is capable of responding to light stimuli, such as those found in the skin or certain parts of the brain. **

Photoreceptor cells are specialized cells in the retina that are sensitive to light and responsible for converting light into electrical signals. There are two types of photoreceptor cells: rods, which are sensitive to low light levels, and cones, which are responsible for color vision. On the other hand, optic nerve cells, also known as ganglion cells, are located in the retina and are responsible for transmitting the electrical signals generated by the photoreceptor cells to the brain via the optic nerve. In summary, photoreceptor cells detect light and convert it into electrical signals, while optic nerve cells transmit these signals to the brain for visual processing. **
