The nucleus is the cell's control centre and contains genetic material. It is the cell's brain, and it is in charge of the majority of its tasks. The cell will not be able to operate correctly if the nucleus is removed, and it will not be able to grow. The cell's metabolic functions will come to a halt. The cell will become incapable of cellular reproduction. The cell will also be unsure of what to do, making cell division impossible.Protein synthesis would also go wrong or inappropriate proteins would be generated, resulting in cell death.
