If you can overwater potted plants in soil, then how come cut flowers don’t drown in vases filled with water?

Plants “breathe” through roots (their leafs are for photosynthesis), so if the soil is so waterlogged that air can’t get to the roots, they “drown”. Cut plants in water are on “life support”. Think of a person who is only surviving because of an IV. After a time, the lack of necessary nutrients and such will still kill them because not everything can be supplied intravenously. That’s why plants that can will start to grow roots, in an attempt to draw in the missing nutrients. But even then, they will eventually drown if not move to proper soil.

Cut flowers don’t have roots any more. Putting them in water helps keep them looking fresh for a while longer but they eventually die after a few days anyways. I know we’re taught that plants convert CO2 to Oxygen and that’s a bit misleading. Plants still need oxygen, and they get that oxygen through their roots. Waterlogged soil prevents any oxygen from getting to the plants and their roots eventually rot and the plant dies. During photosynthesis plants convert CO2 to glucose, and the water from the soil into Oxygen, so it’s not the CO2 being directly converted into Oxygen.
