Why are photodiodes used preferably in reverse bias condition?

Statement-I : A p-n junction with reverse bias can be used as a photodiode to measure light intensity. Statement-II : In a reverse bias condition the current in small but it is more sensitive to changes in incident light intensity.

Give three differences between forward bias and reverse bias.
