Chromatin is unfolded, uncondensed, extended thread like DNA while chromosomes are condensed DNA. Most of the time the genetic material is present as chromatin. When the cell is about to divide, the chromatin threads get organised into chromosomes.
Chromatin is not visible, as individual chromosomal entities, through a light microscope. During cell division each of these individual chromatin condense into a light-microscope-visible chromosome.
