Plasma membrane separates inner compartments of the cells from their external environment. Regulates movements of substances inside and outside the cell. Nucleus is the major site of cellular activities that keeps the cells in a living state. Cytoplasm controls all the cellular activities. Mitochondria is called the powerhouse of a cell because it can generate energy in the form of ATP.
