    Question

    Nitrogen in excess cannot cause enough ______________.

    1. Stem structure
    2. Leaf structure
    3. Root structure
    4. Fruits

    Hint:

    The part of plant which develops from radical.

    The correct answer is: Root structure

      • Roots will not be affected with excess nitrogen
      • Excess of nitrogen enhances the biomass of the plants
      • The plants develop succulent stem and leaves
      • Production of fruits will be reduced and more leaves will be produced instead
      • Roots will contain certain beneficial microbes called rhizobium which is involved in nitrogen fixation
