Re: Why the Sun radiation is ranged along the all electromagnetic spectrum

No, the plasma of the sun emits radiation according to blackbody radiation in addition to having spectral absorption lines from its atmosphere. See here for better details on blackbody radiation: http://hyperphysics.phy-astr.gsu.edu/hbase/mod6.html This is why the Sun appears yellow, its peak output wavelength is in the yellow range because of its temperature. This is known as Wein's law, a simple relationship between the temperature and peak output wavelength of a hot object.
