First they don't use oxygen, plants use the CO2 in the air and release oxygen out into the air after the plant used up the CO2
Plants do need oxygen to survive. They respire (take in oxygen, give off carbon dioxide) the same way that animals do. The difference is that during the day, plants also perform photosynthesis, in which they take in carbon dioxide and give off oxygen.
