Transistors can be PNP or NPN. PN or NP means simply PN junction diode which will act as NOT gate. Not because of the reason stated above to my knowledge.

Because transistor act as a inverter.

NOT Gate is like an inverter it is because when we gives one to the input of not gate we get zero i.e, inverts of the input.

But when gate supply zero how transistor output will be one?

All the above answers not completely true. Answer is. A transistor can be used as a switch. That is, when base is low collector is high (input zero, output one) and base is high collector is low (input 1, output 0).
