I was going to ask about the availability of oxygen and sunlight.

  Oxygen? Don't you mean water? Most plants need some oxygen for the root network, but photosynthesis produces an excess of oxygen and doesn't require it to run.

    Wait for real? My highschool biology class lied to me.

      Didn't your highschool biology teach you that photosynthesis is 6CO₂ + 6H₂O = C₆H₁₂O₆ + 6O₂? That's what I remember from school. Takes light, water and carbon dioxide, makes glucose and oxygen.
