What is the difference between chromatin. chromatids. and chromosomes?

Chromatin: is a complex made up of genetic material (DNA), wrapped in protein , such as histones,present in the cells of eukaryotes.

Chromatids :before the cell divides, the chromosomes are copied, and each chromosome consists of two segments in the form of bat, the chromatids. Each cromátide corresponds to a copy of one of the 46 strands of DNA in every one of my cells (sperm and eggs).

Chromosomes: are present in cells that are in the process of Division. In place of chromatin, we can observe in the nucleus, small bat-shapedbodies quite stained, easily visible when observed under a microscope.

hope this helps!
