Which fertilizer nutrient is responsible for plant cell production and increase in plant maturity?

Which fertilizer nutrient is responsible for plant cell production and increase in plant maturity?

• A. Phosphorus
• B. Nitrogen
• C. Potassium
• D. Iron

Answer: (A)

Phosphorus drives energy transfer and the synthesis of nucleic acids, which are essential for cell division and growth. This makes it the nutrient most linked to new cell production and the progression of tissues toward maturity, including root development and eventual flowering and seed formation. Nitrogen supports leafy, vegetative growth rather than cell production; potassium aids overall vigor and water regulation; iron is needed for chlorophyll but isn’t the primary driver of cell production. So phosphorus best explains the role described.
