Detailed explanation-1: -The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus.

Detailed explanation-2: -The Nucleolus-The nucleolus is a membrane-less organelle within the nucleus that manufactures ribosomes, the cell’s protein-producing structures. Through the microscope, the nucleolus looks like a large dark spot within the nucleus.

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: -Nucleus. The nucleus serves as the cell’s command center, sending directions to the cell to grow, mature, divide, or die. It also houses DNA (deoxyribonucleic acid), the cell’s hereditary material.
