Question

why is the nucleus called the control room of the cell

Answer 1

The genes within these chromosomes are the cell's nuclear genome and are structured in such a way to promote cell function. The nucleus maintains the integrity of genes and controls the activities of the cell by regulating gene expression—the nucleus is, therefore, the control center of the cell.

Answer 2

nucleus is called the control room of the cell or the brain of the cell because all the organelles work only after the command of the nucleus. it also contains chromosomes which are helpful in making protiens which help in many cellular activities.
