A; Must define the transistor type and its mode of application if you expect an answer. It has the capabilities to conduct both way on either type dueing saturation mode. Hope that helps
A transistor is a switch. A diode directs the flow of current.
A: A transistor has voltage gain as base current is allow to flow. If the load is constant then a DC mirror azimuth path can be plotted as a function of base current and collector current and that is the load line
Because a transistor's collector current is proportionally limited by its base current, it can be used as a sort of current-controlled switch. A relatively small flow of electrons sent through the base of the transistor has the ability to exert control over a much larger flow of electrons through the collector.
The base is excited by a very low current. That turns the transistor on so that a higher amount of current flow comes out.
the base circuit
The active region of a transistor is when the transistor has sufficient base current to turn the transistor on and for a larger current to flow from emitter to collector. This is the region where the transistor is on and fully operating.

To allow current to flow in only one direction.

An n-p-n transistor can be used as a switch by controlling the current flowing through its base terminal. When a small current is applied to the base, it allows a larger current to flow from the collector to the emitter, turning the transistor "on." Conversely, when the base current is removed, the transistor turns "off," stopping the current flow. This on-off control allows the n-p-n transistor to effectively switch electrical circuits.

A: The small base current will control the collector current flow by adding a resistor this changes of current flow will be evident as a voltage amplifier.
Only because the circuit that its embeded in is designed that way. Remember, a transistor is basicly an amplifier ... only if you design everything to go to the extreams will it act as a switch.
it indicates the direction of flow of emitter current
That depends on whether you are considering conventional current or electron current.
