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: -A cell’s nucleus is a membrane-enclosed organelle found in eukaryotic cells, which serves as the control center of a cell. It contains the cell’s genetic material in the form of DNA and directs the cell’s activities.

Detailed explanation-3: -By housing the cell’s genome, the nucleus serves both as the repository of genetic information and as the cell’s control center. DNA replication, transcription, and RNA processing all take place within the nucleus, with only the final stage of gene expression (translation) localized to the cytoplasm.

Detailed explanation-4: -The nucleolus is a spherical structure found in the cell’s nucleus whose primary function is to produce and assemble the cell’s ribosomes. The nucleolus is also where ribosomal RNA genes are transcribed.

Detailed explanation-5: -Nucleus-The control center of the cell that directs all of the cell activities. Genetic material is contained inside. Usually found in center of cell. Nuclear Membrane-The outside boundary of the nucleus that controls what enters and exits the nucleus.
