The control center and director of cell activities is the nucleus.
The nucleus is a membrane enclosed organelle and the prominent organelle found in eukaryotic cells. Nucleus is the control center of the cell because it controls all the activities of the cell. Nucleus contains the cell’s hereditary material and is responsible for protein synthesis and cell division. It is surrounded by a nuclear envelope (a double membrane that maintains the nucleus’s shape and control molecules movement within and out of the nucleus).
