  It is widely believed that quantum field fluctuation in an inflating
background creates the primeval seed perturbation which through subsequent
evolution leads to the observed large scale structure of the universe. The
standard inflationary scenario produces scale invariant power spectrum quite
generically but it produces, unless fine tuned, too large amplitude for the
primordial density perturbation than observed. Using similar techniques it is
shown that loop quantum cosmology induced inflationary scenario can produce
scale invariant power spectrum as well as small amplitude for the primordial
density perturbation without fine tuning. Further its power spectrum has a
qualitatively distinct feature which is in principle falsifiable by observation
and can distinguish it from the standard inflationary scenario.
