Explanation / Answer

Cell divides for reproduction, or to promote the growth of a structure, or to replace a dead cell. Cell division plays a variety of roles in a multicellular organism.

Cells spend almost 78% of time in interphase. During this time the cell does not divide.

The chromatin is the DNA that forms a nucleosome binding with histone proteins. Chromatin is present in the nucleus. The chromatin condenses to form chromosomes.

Chromatin is always present in the cell.

Chromosomes are found in the cell during after S phase.
