Answer 8

You have a lot of WRONG answers above saying that grass doesn't need oxygen.  IT DOES, for the same reason you do: to be the electron acceptor at the end of the mitochondrial electron transport chain.  If you starve a plant of oxygen it will die.  In a NET sense, a growing plant will produce more oxygen than it uses, but plants make sugars so they can survive by eating them, which requires oxygen.
