Potassium is absorbed from soil as potassium ions. It helps to maintain an anion cation balance in cells and is involved in protein synthesis, opening and closing of stomata, activation of enzymes and maintenance of cell turgidity.

The mineral present in cell wall is calcium

The manganese activates enzymes involved in photosynthesis and nitrogen metabolism, especially in photolysis of water to release oxygen. All parts of photosynthesis are important, arguably the photolysis of water is the most important reaction in the process.
