The Gate.

FET stands for Field Effect Transistor. The name FET comes because the gate current of a field effect transistor is zero and current present in the source conductor is due to an electric field produced by the substrate material placed between the gate and the source.
A Field-Effect Transistor (FET) can function as a voltage variable resistor by utilizing its gate voltage to control the channel conductivity. By applying a varying voltage to the gate, the FET alters the channel's resistance, allowing it to act like a variable resistor. This property is particularly useful in applications like analog signal processing and voltage-controlled amplifiers, where precise control of resistance is required. The FET's high input impedance also minimizes the loading effect on the preceding circuit, making it an effective choice for such applications.
you want to keep the channel electrically isolated from the gate (jfet) or substrate (mosfet) so that it operates as a fet, don't you? if it was forward biased it would just be a diode with no field effect.

FET is a field effect transistor, abbreviated to FET. There are two basic types of FET: a junction FET abbreviated to JFET and an insulated gate FET , abbreviated to IGFET. The most common type of IGFET is a metal-oxide silicon FET, Known as a MOSFET. Modern microprocessors may contain tens of millions of MOSFETs.

This gate permits electrons to flow through or blocks their passage by creating or eliminating a channel between the source and drain.
It is NMOS FET. PMOS works in a reverse way.
