Explanation:

The nucleus contains the cell's genetic material (DNA). It controls and directs all cellular activities by sending instructions to different parts of the cell through processes like transcription and translation. The cell - wall gives strength and stiffness, ribosomes make proteins, and the cytoskeleton gives structure and organization.
