Below the diode's Forward Voltage (Vf) typically 0.7V, the curve is at (roughly) zero. At around 0.5 it begins to curve upward, and at around 0.7V, the voltage drop is almost constant (the curve heads straight upwards to infinity). See link.
when a diode is forward biased it conducts current
The approximate voltage across the forward-biased base-emitter junction is 0.7 volts.
0.7 The voltage across a silicon diode when it is forward biased should be greater than or equal (>=) 0.7volts.
Because if you forward-biased them they would always conduct, even in total darkness.
The current is nearly zero at a voltage less than 0.4v in a forward biased silicon diode because of the small forward-bias voltage.
characteristics of forward biased
Zero current flow when reverse biased, zero voltage drop when forward biased.

that is a biased question
light up when forward biased
0.7 The voltage across a silicon diode when it is forward biased should be greater than or equal (>=) 0.7volts.
It depends on the particular LED. Some of them emit infrared light. But, yes, emission occurs when forward-biased.
A forward-biased diode has a positive DC on its anode with respect to its cathode.
A nonconducting diode is biased in the reversed direction (reverse polarization).
acts like a normal diode in forward biased condition
A conducting junction.
