Detailed explanation-1: -Nucleus is the control central of the cell. Inside its fully-enclosed nuclear membrane, it contains the majority of the cell’s genetic material. Only eukaryotes have a well defined membrane bound nucleus.

Detailed explanation-2: -The presence of a nucleus is the principal feature that distinguishes eukaryotic from prokaryotic cells. By housing the cell’s genome, the nucleus serves both as the repository of genetic information and as the cell’s control center.

Detailed explanation-3: -Because nucleus contains a material called gene which controls all activities of cell and its characteristics. Cell nuclei contain most of the cell’s genetic material, organized as multiple long linear DNA molecules in complex with histones, to form chromosomes.

Detailed explanation-4: -The nucleus is the largest and most significant living organelle of the cell. All cell activities of the cell are regulated by the nucleus. Hence it is called brain or control centre of the cell.

Detailed explanation-5: -The main function of nucleus in eukaryotic cells is to protect the DNA. The nucleus separates the DNA from the rest of the cell and keeps it safe. The nucleus also regulates what enters and leaves.
