Detailed explanation-1: -Magnesium is the central core of the chlorophyll molecule in plant tissue. Thus, if Mg is deficient, the shortage of chlorophyll results in poor and stunted plant growth. Magnesium also helps to activate specific enzyme systems.
Detailed explanation-2: -Chlorophyll a contains a magnesium ion encased in a large ring structure known as a chlorin. The chlorin ring is a heterocyclic compound derived from pyrrole. Four nitrogen atoms from the chlorin surround and bind the magnesium atom. The magnesium center uniquely defines the structure as a chlorophyll molecule.
Detailed explanation-3: -ATP binds to magnesium ion (Mg2+) to compose biologically functional form, and most of intracellular ATP and Mg2+ assumed to form Mg-ATP complexes. Because both ATP and Mg2+ are mutually and strongly buffered in cytosol, it had been believed that Mg2+ deeply contributes on energy metabolism.
