Detailed explanation-1: -Nucleus. Known as the cell’s “command center, ” the nucleus is a large organelle that stores the cell’s DNA (deoxyribonucleic acid). The nucleus controls all of the cell’s activities, such as growth and metabolism, using the DNA’s genetic information.

Detailed explanation-2: -The nucleus is often referred to as the control center, or brain, of the cell and contains the DNA, or genetic material. The nucleus is surrounded by the nuclear envelope.

Detailed explanation-3: -Nucleus and Nucleolus The nucleus, formed by a nuclear membrane around a fluid nucleoplasm, is the control center of the cell. Threads of chromatin in the nucleus contain deoxyribonucleic acid (DNA), the genetic material of the cell.

Detailed explanation-4: -Nucleus acts as ‘brain’ of the cell. It regulates and controls all the cell activities.

Detailed explanation-5: -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.
