Certain elements perform different metabolic functions like maintaining cell permeability, maintaining concentration of the cell sap, performing buffering actions and acts as constituents of the major macromolecules.

Molybdenum participates in nitrogen metabolism.

Zinc participates in the auxin synthesis for plant growth and development.

Calcium helps in maintaining the normal functioning of the cell membrane and also helps in the formation of mitotic spindles.

Potassium regulates the opening and closing of stomata and also helps in the protein synthesis.
