Hello!
The tangled mass of network tangled together and distributed in the nuclear plasm is called the chromatin network. During cell division this chromatin network condenses to form which ribbon like structures called chromosomes. They contain the hereditary materials called genes.

In the nucleus, the DNA double helix is packaged by special proteins (histones) to form a complex called chromatin. The chromatin undergoes further condensation to form the chromosome. So while the chromatin is a lower order of DNA organization, chromosomes are the higher order of DNA organization. An organism’s genetic content is counted in terms of the chromosome pairs present. e.g. humans have 23 pairs of chromosomes.
