How does the nucleus, EPS and mitochondria ensure the integrity of the cell?

Each part of the cell performs a specific function. The nucleus stores hereditary information in chromosomes, namely, in DNA molecules. If any protein is needed in the nucleus, i-RNA is synthesized, and through the pores in the nucleus it enters the cytoplasm. On the surface of the granular EPS, there are ribosomes that synthesize protein for a given m-RNA. Fusion requires energy. It is provided by mitochondria. The formed protein enters the EPS and moves to the part of the cell where it is needed. Everything is interconnected.
