Explanation:

The nucleus is the part of the cell that contains DNA (in the form of chromosomes) and acts as the control center of the cell. It regulates gene expression and cellular activities. Mutations in DNA within the nucleus can lead to uncontrolled cell growth, a hallmark of cancer. The cytoplasm is the jelly - like substance inside the cell where organelles are suspended. The cell membrane is the outer boundary that controls what enters and exits the cell. Mitochondria are the powerhouses of the cell, responsible for energy production.
