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: -Nuclei contain the genetic material called DNA that is responsible for controlling and directing all cell activities.

Detailed explanation-3: -Structure of the Nucleus The cell nucleus consists of a nuclear membrane, called the nuclear envelope, nucleoplasm, nucleolus, and chromosomes. Nucleoplasm, also called karyoplasm, is the matrix present inside the nucleus. The nuclear membrane separates the constituents of the nucleus from the cytoplasm.

Detailed explanation-4: -1. DNA is stored in the nucleus of a cell. 2. The nucleus of an atom consists of neutrons, protons and other particles.

Detailed explanation-5: -Nucleus: The nucleus is the most important organelle of the cell which controls all the cellular activity. It contains the genetic material in the form of DNA which is protected by the nuclear envelope.
