      but this is such a common misconception among biology students that I can't resist.

      Plants do both.  Their cells oxidize organic molecules to generate ATP (i.e. useable energy) and give off CO2 as a waste product while consuming O2.  Cellular respiration just like animals.

      Plants also perform photosynthesis which is essentially the same process in reverse.  Overall they do more photosynthesis than respiration (hence plants grow and reproduce) but they definitely do both processes.

      As demimondian points out plants are net consumers of O2 and producers of O2 at night.
