Why is it important for each daughter cell to contain information identical to the parent cell?

2. organelles must work together and their activities be cordinated. 

this is the best suitable statement in this case, as organelles cannot operate independently of one another. each organelle can only perform a specific function and each function cannot restore homeostasis of the cell. hence, a series of processes performed by different organelles causes restoration of homeostasis in the cell. for instance, production of proteins is also a process which involves the working of two different organelles, the nucleus and the ribosomes.
