Because the LDR has high resistance. This makes the voltage at
the base of the transistor too low to turn the transistor ON.

to function as the trigger for a larger emitter-to-collector
current. When the base current receives sufficient current, a
larger current then flows from the emitter to the collector.
When the base of the transistor receives sufficient current, the
charge carriers from the emitter are attracted to the holes in
the base region. This creates an avalanche effect in which the
current continues on to the collector region, which the large
current outputs through.
