While we often think of plants only as oxygen producers via photosynthesis, they are equally dependent on respiration for energy. Respiration is the biological oxidation of complex organic molecules (like glucose) to release energy in the form of ATP. This energy drives every cellular activity, from growth and nutrient uptake to reproduction.
