how does a cell know which genes to turn on when?

Mostly unknown: We are aware that this happens and that the cell grows and matures by turning on and off genes. The biochemical means by which this is done is mostly unknown and is the subject of intense research. The answer to this probably will allow much improved therapy and probably ways to treat conditions such as cancer which involves the wrong genes being activated.
