Ions

• Nitrate


  . Nitrogen/nitrate (NO3-)

  . Amino acids for proteins and nucleotides for DNA

  . A lack of causes yellow leaves and stunted growth
• Phosphate


  . Phosphorus/Phosphate(PO4³¯)

  . Making DNA and cell membranes, used in ATP for respiration

  . A lack of causes poor root growth and younger leaves turn purple
• Ions


  Ions help create biomolecules containing the element, the ions are just usable forms of the element
• Potassium


  . Potassium(K+)

  . Help enzymes needed for respiration and photosynthesis

  . If lack of, leaves turn yellow with dead spots aswell as poor flower and fruit growth
