  • Oxygen release is the main purpose of photosynthesis.
  • Plants consume oxygen to produce carbon dioxide. 

  • Respiration takes place only in leaves where the special apertures (pores) for the exchange of gases take place.

  • The most important source of nutrients for the plant is that water with dissolved substances that are absorbed through the root system.
