Why does changing the water in a vase extend the life of cut flowers?

I don’t understand why flowers last longer if you change the water every day but fall apart if they are left in a full vase of water from yesterday. Are they removing nutrients from the water?

The bacteria that develops over time rots the ends of the stems causing them to no longer take in water. Changing the water and snipping the ends helps trim away at the dead material not taking in nutrients and exposing the parts of the stem that can.
