Plants don't "breathe in" oxygen, but carbon dioxide.
If the plant is deprived of CO2, it will grow slower and smaller (becuase it has less CO2 to make food).
If completely cut off from CO2 the plant would eventually die.

Basically plants only need oxygen at night for cellular respiration. Plants use carbon dioxide during the day and have no need for oxygen. The gas exchange: absorption/emission takes place in the stomata, or pores in the leaves if it is a vascular plant as the majority of plant species are.

Plants require CO2 carbon dioxide for respirationa and give off O2oxygen as a by product of respiration so oxygen deprivation is not a factor for plants.
