What is the effect of a pure-oxygen environment on a plant?



Just read What's the effect of oxygen deficit on plants? ; and wondered whether the opposite would have any effect on a plant.


That is to say, if a potted plant were placed under a bell-jar and the air within replaced by pure oxygen would the plant starve? If the environment/soil were loosely radioactive, would it make a difference?



Answer



Ask yourself, where would the plant take the carbon for construction of all kind of molecules, most important the cell membrane and cell wall of newly divided cells. Plants do not eat! So they have to get their carbon from somewhere else.
