Photoresistor also is known as LDR(Light Dependent Resistor) as the names imply, changes the resistance with the variation in the amount of light. This particular photoresistor has a resistance of 5-10k Ohm in light and about 500k Ohm resistance in the dark. 

The LDR 5mm Light-Dependent Resistor PhotoResistor sensor works best in both Light and dark regions. Light-dependent resistors or photoresistors are a staple of electronics. If you need a way to sense the level of ambient light then there is no easier way to do it. As the light on the sensor increases then the resistance across the two leads decreases. Two Cadmium Sulphide (CDs) PhotoConductive Cells with spectral responses similar to that of the human eye. Cell resistance falls with increasing light intensity.
