Which nutrient is primarily involved in energy transfer within plant cells?

Explanation:
Energy transfer in plant cells hinges on ATP, the molecule that stores and releases energy through phosphate bonds. Phosphorus forms these phosphate groups, and energy is released when ATP becomes ADP and inorganic phosphate to power cellular activities. So phosphorus is the nutrient most closely tied to energy transfer. Other nutrients have important roles too—nitrogen helps build amino acids and chlorophyll, potassium supports enzyme activity and osmotic balance, and iron is key in electron transport—but none serve as the primary energy currency the way phosphorus does.
