Photosynthesis

• Plants use the process of photosynthesis to convert light into food, but light can damage plants by excessively raising their temperature. Vitamin C combats this damage, which increases the overall metabolism rate.
  
  

Enzymes

• Vitamins B-1 and B-6 have been shown to increase enzyme production, which directly governs a plant's metabolism.
  
  

Smog Damage

• Plants that were introduced to vitamin C with their normal food supply have shown an increased resistance to damage from smog and other air impurities. This resistance often leads to faster growth and higher crop yield.
  
  

Potassium

• Potassium exists naturally, making up two percent of the Earth's crust. The correct level of potassium in soil can dictate the growth of certain plants.
  
  

Magnesium

• Magnesium also occurs naturally in soil and plays an important role in the formation of ATP and ADP, which affects the metabolism of all plants.
