The cell nucleus is a structure or organelle in eukaryotic cells that is usually placed in the center of the cell. The nucleus is important because in this the genetic material is contained and also the nucleus is the one that commands, controls and coordinates the activities that occur in the cell including reproduction, growth, metabolism, among others. This means the nucleus is the control center of the cell and therefore, the option that describes the function of the cell nucleus is "command and control".
