We know that photosynthesis produces oxygen and cellular respiration 
produces carbon dioxide.  Can these molecules be used by the plant cell 
(for cellular respiration and photosynthesis respectively) without being 
released into the atmosphere first?  If not, how does the plant get the 
oxygen in and to its cells?  Is it through the same stomata through which 
carbon dioxide enters?  I know some oxygen enters through the roots but is 
this somehow transported to the leaves?  Thanks!
