The correct answer is

Chlorophyll molecule

Chlorophyll has a structure that includes magnesium. Magnesium has the atomic number 12 and the symbol Mg. 

  • Magnesium was given the name "magnum" by Sir Humphry Davy when it was first isolated in 1808. 
  • Inconsistent magnesium was first prepared by Antoine Bussy in 1831. 
  • Magnesium is an alkaline earth metal that can be found in large deposits in the form of dolomite, magnesite, and other minerals. 
  • It is not naturally present in its free pure form.
  • The central core of the chlorophyll molecule in plant tissue is magnesium. 

As a result, if Mg is inadequate, the lack of chlorophyll causes poor and stunted plant growth. Magnesium also assists in the activation of particular enzyme systems. Enzymes are intricate substances that are used in the normal metabolism of plants to build, alter, or break down compounds. Magnesium makes up 13% of the mass of our planet and is the eighth most abundant element in the crust.
